isonicotinic acid/breast neoplasms

Amont 338 women treated in Massachusetts with isoniazid (isonicotinic acid hydrazide = INH) for pulmonary tuberculosis, no excess cancer deaths occurred (8 observed vs 8.3 expected) after 23 years (12.9 mean) of follow-up. There was an excess of cancer deaths (54 vs 35.7) among 1,090 patients who

In this study, we present the evaluation of two new ternary ligand (99m)Tc complexes [(99m)Tc(HYNIC tetramer)(tricine)(L)] [L=isonicotinic acid (ISONIC) and 2,5-pyridinedicarboxylic acid (PDA)] as potential radiotracers for tumor imaging. Athymic nude mice bearing MDA-MB-435 human breast cancer

This report describes biodistribution characteristics of three ternary ligand complexes [(99m)Tc(SQ168)(tricine)(L)] (SQ168 = [2-[[[5-[carboonyl]-2-pyridinyl]hydrazono]methyl]-benzenesulfonic acid]-Glu(cyclo{Lys-Arg-Gly-Asp-d-Phe})-cyclo{Lys-Arg-Gly-Asp-d-Phe}; L = TPPTS (trisodium

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Δ² -pyrazoline analogs as novel Hsp90 inhibitors by integrated
