The effect of the oral administration of 10 compounds on 1,2-dimethylhydrazine (DMH) carcinogenesis was investigated in 180 male Wistar rats and 510 male BD6 rats. DMH, administered s.c. once per week for 20 consecutive weeks (20 mg/kg body wt/dose), produced intestinal (mainly colon) tumors of

Cardiovascular diseases are the most important cause of mortality in industrialised countries. Contrary to cancer research, cardiovascular research mostly ignores toxic effects, apart from nicotine, caffeine, alcohol, a few pharmaceutical drugs, and the (in our countries) minor workplace problems

Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time

The novel heterocyclization of 5-(2-aminophenyl)-1H-tetrazole with potassium ethylxanthogenate or carbon disulfide was proposed. The potassium salt of the tetrazolo[1,5-c]quinazoline-5-thione was subsequently modified by alkylation with proper halogen derivatives to

Synthesis and evaluation of 3-(benzylthio)-5-(1H-indol-3-yl)-1,2,4-triazol-4-amines as Bcl-2 inhibitory anticancer agents.

A series of substituted 3-(benzylthio)-5-(1H-indol-3-yl)-4H-1,2,4-triazol-4-amines has been synthesised and tested in vitro as potential pro-apoptotic Bcl-2-inhibitory anticancer agents. Synthesis of the target compounds was readily accomplished in good yields through a cyclisation reaction between

Volatile organic compounds (VOCs) are ubiquitous in the environment, originating from many different natural and anthropogenic sources, including tobacco smoke. Long-term exposure to certain VOCs may increase the risk for cancer, birth defects, and neurocognitive impairment. Therefore, VOC exposure
