Gossypol Acetate Chemical Structure

CAS No. 12542-36-8

Gossypol Acetate (Gossypol Acetic acid, Pogosin, AT101) is a polyphenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes such as lactate dehydrogenase, NAD-linked enzymes.

  • 16h after seeding HMLE RAS cells were exposed to 5 uM or 10 uM Gossypol in the presence or absence of Cisplatin for 16h. Afterwards, cells were harvested and lysates were analyzed for apoptosis by western blotting. Actin staining was used as loading control, while LC3a/b staining was used as indicator for autophagy. Accumulation of LC3a/b II indicates autophagy. Non-treated and DMSO-treated cells were used as control. Arrows are indicating the intended staining. For Bcl-xL: * indicates deamidated protein, # indicates unmodified protein. n=1.

    Weight gain of Spodoptera littoralis larvae on combined Cry proteins and gossypol. Weight gain (mg ± SE) of 2nd instar S. littoralis after feeding for one week on diet containing different concentrations of Cry proteins, gossypol, or a combination of both. Control = diet with added PBST; C1 = Cry1Ac 0.05 + Cry2Ab2 1.6 pmol/g; C3 = Cry1Ac 0.52 + Cry2Ab2 16.4 pmol/g; C4 = Cry1Ac 1.7 + Cry2Ab2 54.5 pmol/g; G3 = 1.3 μmol/g gossypol. Asterisks indicate significant difference to the control diet using a GLM with gamma distribution followed by Dunnett`s Test (n = 53-60). *** p ≤ 0.001.

  • H9c2 cells were incubated with indicated bioactive compounds for 2 hours prior to protein harvest. Cells were lysed and acetyl-lysine (Ac-Lysine), acetyl-histone 3 (Ac-H3 K9/14) and total histone 3 (Total-H3) were assessed via immunoblot. Acetylation of lysine and Ac-H3 (K9/14) increased for gossypol. Acetyl proteins were normalized to total H3 and quantitation performed via Image J software.

  • Effect of AT-101 (AT) on MM cell lines survival. The survival of human (MM-B1, H-Meso-1, and MM-F1) and mouse (#40a) MM cell lines were assessed by the SRB assay after 24, 48, and 72 h of treatment with DMSO or AT-101. The percentage of surviving cells treated with the compound was calculated by normalizing the OD value to that of the control cultures (DMSO). The results are expressed as the means ± SD of three independent experiments performed in triplicate (xp ≤ 0.05, ∗p ≤ 0.01, #p ≤ 0.001 compared with the cultures treated with DMSO).

Biological Activity

Description Gossypol Acetate (Gossypol Acetic acid, Pogosin, AT101) is a polyphenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes such as lactate dehydrogenase, NAD-linked enzymes.
Dehydrogenase [1] Bcl2 [5]
In vitro

Gossypol, a known antispermatogenic agent from the cotton plant genus Gossypium, was found to inhibit yellow perch sperm motility in vitro and lactate dehydrogenase activity in spermatozoa when used in a dose-dependent manner[1]. Gossypol has been approved to have antiproliferative and apoptosis-inducing effects on some kinds of cancer cell lines in vitro[2].

In vivo Gossypol acetate is able to inhibit tumor growth in Wus1-bearing mice, but the survival of mice is not prolonged, and tumor grows rapidly after short inhibition. Gossypol has now been found to have inhibitory effects on proliferation or to induce apoptosis in ovarian cancer, endometrial cancer, adrenal cortical tumor, thyroid cancer, lung cancer, colon carcinoma, leukemia, pancreatic cancer, melanoma and lymphoma. In addition, gossypol can increase the sensitivity of drug-resistant tumor cells to chemotherapy and radiotherapy. Some clinical trials showed gossypol is well-tolerated, and partial responses are observed in some patients[4].

  • Cell lines: Human MM cell lines U266 and Wus1
  • Concentrations: 1, 5, 10, 25 and 50 µmol/l
  • Incubation Time: 0, 24, 48 and 72 h
  • Method:

    MM(Multiple myeloma) cells are plated in 24-cell culture clusters at a density of 1x105 viable cells/l per well. Triplicate wells are treated with 1, 5, 10, 25 and 50 µmol/l gossypol acetate, and the negative control group is supplemented with 0.1% DMSO. Then, cell numbers at different treatment time points (0, 24, 48 and 72 h) are determined by using a hemocytometer and the trypan blue dye-exclusion method. The trypan blue dye-exclusion method is used to evaluate the cell viability. The cells are examined in a counting chamber under a light microscope. Only viable cells are recorded.

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.
