CANCER AND CDK INHIBITION

3215 | Sep 16 2012

CDK/CYCLIN DEPENDENT KINASES: Among a large number of cell cycle regulators, cyclin dependent kinases also known as CDKs are known to be very important ones. These kinases play a crucial role in the processes of transcription, mRNA processing and cellular differentiation. These kinases have a small structure with an important kinase domain and depend on another small protein for proper activity i.e., cyclin. As these are very important kinases in cell cycle, they can be targeted in order to prevent proliferation of cancer cells. Inhibition of these kinases has shown induction of apoptosis especially in cancer cells. Various inhibitors have been designed against different kinases to fight cancer and inflammation, preserved in kinase inhibitor library for screening amongst these CDK2 inhibitors have been found to be most effective. Inhibiting cell cycle regulators may have some hazards as well; therefore inhibitors should be developed carefully in order to avoid these side effects. [Read the Full Post]

PATHWAY OF HSP90 AND CANCER CELL LINES: Heat shock protein 90 or Hsp90 is actually a non-fibrous protein which gained its name from its molecular weight that is 90kDa. Hsp90 is most abundant cytoplasmic protein which plays a significant role in cells by acting like a molecular chaperone for many proteins related to some important signaling cascades of the cell. Different proteins chaperones that are existing in the cell, involve serine/theronine kinases and tyrosine kinases as well hence they are very much important for the proper regulation of cell growth and cell cycle. A detailed research is carried out to describe the relation between Hsp90 and cancers. To inhibit this chaperone i.e. Hsp90, the simple strategy of designing Hsp protein inhibitor was developed when Hsp90 was found to be existing in different cancerous cell lines activated through the activation of oncogenes. It has been proved a very fruitful therapy for cancer. [Read the Full Post]

PACLITAXEL – MULTIPLE ROLES AS MICROTUBULE STABILIZER

3210 | Mar 19 2012

Introduction: Mitosis and Cytokinesis An essential part of the cell cycle is the M phase where the cell physically divides into two unique cells. This process is consists of two different phases mitosis and cytokinesis. Cytokinesis is the phase where the contents of the cell are divided into two equal portions along with the duplicate chromosomes and nuclei. The cell membrane then pinches together and eventually splits into two segments. Mitosis, on the other hand is the division of the duplicate chromosomes and nuclei into opposite ends of the cell. To do this; microtubule form from one end of the elongated cell to the newly formed chromosomes, these tubules then decrease in length pulling the chromosomes pairs apart. The same happens for the nuclei. This process is complex and involved but it is sufficient to indicate that action of inhibitors against the dismantling of the microtubules would halt the cell separation causing apoptosis to initiate. A small molecule that can induce such a reaction is Paclitaxel microtubule stabilization has been used as the standard treatment for a variety of cancer types for many years. [Read the Full Post]

HSP INHIBITORS AGAINST PROTEIN FOLDING

4101 | Mar 19 2012

Introduction: Cellular Quality Assurance The network of chemical reactions linked to the mechanisms behind cellular growth, proliferation and differentiation are complex. Referred to as biochemical pathways these mechanisms operate on some simple principles starting with the receipt of a message from the host system to the cell itself. The pathway system can be likened to a production line facility with the product being a normal health cell. So mechanisms exists for stock piling of raw materials, for the synthesis of component parts, for the recycling of waste materials, for the removal of unwelcome molecules, quality assurance and final product viability. One the key aspects of cellular growth is the delicacy of the whole process, it does not take much to drive a mechanism off balance and produce a faulty product, to ensure quality under stress induced conditions a series of proteins exist referred to as Heat Shock Proteins that assess the quality of proteins being constructed for cell growth purposes.

CDK INHIBITORS IN REGULATING CELL CYCLE

2429 | Mar 20 2012

Introduction: Cyclin dependent Kinases In total 512 human versions serine/therione/tyrosine kinases have been discovered leading to the theoretical formation of multiple pathways that govern all aspects of cellular life and death. Research has confirmed many of these controls but aspects of these mechanisms still remain controversial. One of earliest kinase pathways to be discovered was the Cyclin dependant kinases. These kinases were shown to be a major regulatory mechanism of the cell cycle growth patterns, apoptotic processes, pain, gene transcription, and RNA formation. Mechanisms with which CDK action and response is controlled can be by phosphorylation or degradation, natural inhibitory proteins, movement of the kinase around the cell or nucleus and by formation complexes with other regulatory proteins.

ROSCOVITINE – A CONTROLLER OF THE CYCLINS

1811 | Mar 20 2012

CDKs AND CANCER: In cellular regulation which is one of the important processes, different enzymes are important and among these cyclin dependent kinases or CDKs play vital role. Mostly cancers are linked with malfunctioning of these CDKs. There are two forms of these malfunctioning, one is the over expression of the CDKs gene and second is about the regulatory proteins of CDKs which may be absent or abnormal. In the field of cancer treatment various inhibitor have been developed which inhibit the function of different vital enzymes. In case of CDKs the development of the unique compound to inhibit the activity of abnormal enzymatic activity is not as simple because the activity of different CDKs is time specific in the cell cycle, therefore a molecule should be well timed up with CDKs. A good number of CDK inhibitors are developed and are mostly in clinical trials phases among those Roscovitine CDK inhibitor is active inhibitor. [Read the Full Post]

THIAZOVIVIN: THE PLURIPOTENCY INDUCER

4428 | Mar 20 2012

POTENTIAL OF EMBRYONIC STEM CELLS OF HUMAN (hESCs): The stem cells are not only known for their property of pluripotency in nature which means they have the potency to replicate in an indefinite manner but also famous for their capability of getting differentiate into all other kinds of cells and organelles from the three basic germinal layers named as ectoderm, mesoderm and endoderm. Embryonic stem cells of human (hESCs) have the ability of producing various numbers of types of cells in contrast to adult stem cells having the capability of producing only a limited cell types. Due to their pluripotency hESCs or human embryonic stem cells are of great interest and importance for the scientists and researchers as they are being used for detection and analysis of different genetic disorders of human in their research. The successful models of Human Embryonic Stem Cells are made for Fragile-X syndrome and Cystic fibrosis (CF) etc like genetic maladies and their will be many more in upcoming years. In olden years the usual practice was to use embryo to generate pluripotent stem cells which is brought down very significantly due to the process of insertion of various genes like Sox2, Oct4 and Klf4 etc into differentiated cells. These genes can enhance the pluripotency in differentiated cells and make them exactly like embryonic stem cells. A recent more advanced approach is to use molecules like Thiazovivin.

TAXOL: BEFORE AND NOW

2597 | Mar 18 2012

Inhibition of cell division A well know cellular function is that of mitosis; which is the biological function whereby a cells nucleus splits into two identical units. The process is accompanied by cytokinesis where the cell membrane, cytosole and separate nuclei divide into to cells. This complete process is referred to as the”M” phase in the cell cycle theory. The complete process is supported by a scaffolding type structure called microtubules which provide the framework for cytokinesis and mitosi. A mitotic inhibitor is one which interferes with the stability of the microtubules which is of relevance in chemotherapy since unregulated cell division is one the strongest difference between tumor and normal cells. This difference can be exploited by a specifically designed inhibitor. Taxol, more commonly called Paclitaxel, is an inhibitor which disrupts the dismantling of the microtubules during cell division, hence cell mitosis cannot occur. Taxol is standard therapy in many forms of cancer including sarcoma, breast cancer, NSCLC, SCLC, ovarian cancer as well as head and neck cancer. [Read the Full Post]

CDK INHIBITOR AGAINST CELL CYCLE DYSREGULATION

1978 | Mar 19 2012

The cell Cycle One of the most important discoveries of the 20th century was the revelations of how cells were governed and regulated in their growth patterns. This process was described in a cell cycle pathway along with regulatory mechanism and quality control functions. Each individual cell is capable of replicating itself but is not always in the processes of doing so. This resting state is referred to as the G0 phase. An extracellular signal is sent to the cell via the cell surface receptors that trigger the cell to enter the G1 phase. This is the first step in cell replication and the cell gathers nutrients as well as protein building blocks from the systemic circulation, this allows the cell to increases in size. Control proteins regulate the amount of material gathered by the cell and the size to which in grows. If certain specifications are met the cell moves from the G1 phase to the S phase of the process.

PD 0332991 – THE POTENT CDK INHIBITOR

3059 | Mar 19 2012

PD 0332991 PROPERTIES: One of the most important functions any cell can do is the reproduction of itself, identical down to the finest degree. The process that achieves the basic necessity of life itself is called the cell cycle and is a highly controlled / regulated process. This process is divided into two stages; the first is the interphase stage which has four distinct phases. The second stage is the cell division stage and this consists solely of the cell mitosis. Starting at stage 1 the cell is usually at rest or in a condition where no replication is occurring, this is referred to as the G0 phase. When a cell receives an external trigger to divide the cell moves into the G1 phase, here the cell will accumulated nutrients and molecules necessary for the construction of all the components of a new cell. Cells use this material to increase in size to accommodate the new material and to generate sufficient cell membrane so a division can occur. The G1 phase has control mechanisms to recognize the successful completion of all necessary components of this phase. [Read the Full Post]

AZD1152 – AN AURORA KINASE INHIBITOR

5551 | Mar 13 2012

Inhibition of AURORA KINASES in relation to cancer: Mitosis is a key process in the regeneration of cellular material and two key regulators of this function are serine and threonine kinases which are more commonly known as Aurora Kinases. Three isoforms of the aurora kinase have been isolated in human tissue (A,B and C) which function on different aspects of the mitosis cycle. Aurora kinases are significant as targets for chemotherapeutic action since they are elevated in many different cancer types. Small molecule inhibitors of aurora kinases, such as VX-680 (Tozasertib), ZM447439 and Hesperadin, have been developed and successfully trialed on several cancer groups including breast, colon, prostate and in acute myeloid leukemia (AML).

ROSCOVITINE – CONTROLLING THE CYCLINS

2948 | Mar 13 2012

Introduction: Cyclin-dependant kinase Inhibitors: Another family of proteins that are involved in the regulation of cellular growth are the cyclin dependant kinases (CDK’s). These enzymes are known to be involved in the regulation of the cell cycle (Mitosis (M phase) – Gap phase (G1) – Synthesis (S) – Gap phase (G2)) as well as regulating transcription, mRNA and differentiation of nerve cells. CDK’s contain not much more than a kinase domain and are serine / threonine phosphorylators. The substrate for CDK’s is a regulatory protein called cyclin of which 12 are known. The activity of CDK’s is restricted to the CDK – complex which in human cells there are at least 9 known variations. Different CDK-complexes are involved at different stages of the cell cycle process each one controlling one or more factors. In current theory CDK’s are the diving motivation behind each phase of the cell cycle and deviations in the CDK activity from the normal can cause unregulated proliferation or simple a tumor. Hence direct targeting of the aberrant CDK activity would ideally be a therapeutic possibility. However, with CDK activity essential for all cell cycle processes there was no theoretical distinction between tumor and normal cells hence significant toxicology could be expected. Recently new research changed this theory; it indicated that tumor cell cycle was controlled by an interphase CDK that was specific to the tumor cell. With this inhibitors of CDK activity could now be implemented against tumor growth patterns. For this purpose smaal molecule inhibitors were designed, of which the Roscovitine CDK inhibitor is one of several being tested in certain tumor types. [Read the Full Post]

TOZASERTIB IN CLINICS FOR AURORA INHIBITION

5208 | Mar 13 2012

AURORA KINASE INHIBITION AND TOZASERTIB:  Three isoforms of the aurora kinase have been isolated in human tissue (A,B and C) which function on different aspects of the mitosis cycle. Aurora kinases are significant as targets for chemotherapeutic action since they are elevated in many different cancer types. Small molecule inhibitors of aurora kinases, such as VX-680 (Tozasertib), ZM447439 and Hesperadin have been developed and successfully trialed on several cancer groups including breast, colon, prostate and in acute myeloid leukemia (AML). The initial results obtained for the Tozasertib Aurora kinase inhibitor has lead to its advancement into phase 1 and phase 2 clinical trials. [Read the Full Post]

The combination of VE-465 and vincristine, the potential therapy for leukemia

7271 | Oct 25 2011

Leukemia is a type of cancer of the blood or bone marrow characterized by an abnormal increase of white blood cells, and studies on the treatment of the disease have been carried out for many years. At present, a variety of small-molecule agents targeting specific leukemogenetic molecules have been used in preclinical or clinical treatment of leukemia. For example, BCR/ABL kinase inhibitors, including imatinib, nilotinib and dasatinib have shown the effective treatment against BCR/ABL-positive leukemia. However, novel agents and therapy may be still needed, since monotherapy shows only limited clinical efficacy. [Read the Full Post]

Roles of Hsp90 in wound healing and cancer

5324 | Oct 24 2011

Wound healing is an intricate process in which the skin (or another organ-tissue) repairs itself after injury. At present, local growth factors are considered to be the driving force for wound healing and only recombinant human platelet-derived growth factor-BB (PDGF-BB) has been approved by US FDA for topical treatment of diabetic ulcers. However, the use of PDGF-BB in clinical trials has been limited for its modest efficacy, high cost and risk of causing cancer. Thus, novel treatment for wound healing is needed to be explored.
