Expression of CD24 and CD44 in HSP90 inhibitor‐treated, shRNA‐transduced HCC1937 cells was analyzed by flow cytometry.
Cancer Sci, 2018, 109(2):373-383. HSP990 (NVP-HSP990) purchased from Selleck.
Time killing curves of C. albicans 103 treated with HSP990 and FLC. FLC-resistant C. albicans 103 were treated with FLC (4 μg/ml), HSP990 (8 μg/ml and FLC+HSP990 (4+8) μg/ml by using initial inoculums of 105 CFU/ml. Aliquots were obtained at the indicated time points and serially dilutions were spreaded on SDA agar plates. Colony counts were determined after 48 h incubation.

| In vitro |
NVP-HSP990 is based on a 2-amino-4-methyl-7,8-dihydropyrido[4,3-d]pyrimidin-5(6H)-one scaffold, which is structurally distinct from other known HSP90 inhibitors. NVP-HSP990 binds to the N-terminal ATP-binding domain of HSP90. NVP-HSP990 exhibits single digit nanomolar IC50 values on three of the HSP90 isoforms (HSP90α, HSP90β, and GRP94) and 320 nM IC50 value on the fourth (TRAP-1), with selectivity against unrelated enzymes, receptors, and kinases. NVP-HSP990 dissociates the HSP90-p23 complex, depleted client protein c-Met, and induced Hsp70 in c-Met amplified GTL-16 gastric tumor cells. NVP-HSP990 potently inhibites the growth of human cell lines and primary patient samples from a variety of tumor types. [1] NVP-HSP990 displays dose- and time-dependent effects on HSP90 client proteins. NVP-HSP990 inhibits Glioma tumor-initiating cells (GIC) proliferation in all GIC lines, with IC50 values ranging approximately between 10 and 500 nM. Olig2 is a functional marker associated with cell proliferation and response to NVP-HSP990, as NVP-HSP990 attenuated cell proliferation in Olig2-high GIC lines. In addition, NVP-HSP990 disrupted cell-cycle control mechanism by decreasing CDK2 and CDK4 and elevating apoptosis-related molecules. [2] |

| In vivo | NVP-HSP990 exhibits drug-like pharmaceutical and pharmacologic properties with high oral bioavailability. In the GTL-16 xenograft model, a single oral administration of 15 mg/kg of NVP-HSP990 induced sustained downregulation of c-Met and upregulation of Hsp70. In repeat dosing studies, NVP-HSP990 treatment resulted in tumor growth inhibition of GTL-16 and other human tumor xenograft models driven by well-defined oncogenic HSP90 client proteins. [1] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
