Chemical Properties

Storage & Solubility Information

Description	Gossypol acetic acid (AT101), a polyphenolic compound isolated from cottonseeds, binds with Bcl-2, Bcl-xL, Mcl-1, and does not inhibit BIR3 domain and BID.
Targets&IC50	BCL-XL:0.5-0.6 μM (Ki), BCL2:0.2-0.3 mM (Ki)
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 Clinicalal trials showed gossypol is well-tolerated, and partial responses are observed in some patients[4].
Cell Research	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.

See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
