C75 (10-50 M) also reduces

5、 the growth ofLNCaP spheroids in a concentration-dependent manner with an IC50 of 50 M 1. (-)-C75 inhibits FASactivity and has a cytotoxic effect on tumor cell lines, without affecting food consumption. (+)-C75 inhibitsCPT1 and its administration produces anorexia, suggesting that central inhibition

6、 of CPT1 is essential for theanorectic effect of C75. The differential activity of C75 enantiomers may lead to the development of potentialnew specific drugs for cancer and obesity 2.體內(nèi)研究 C75 blocks fasting-induced c-Fos expression in the arcuate nucleus (Arc), lateral hypothalamic area (LHA),and pa

C75-treated DIOmice has a 50% greater weight loss, and a 32.9% increased production of energy because of fatty

8、acidoxidation. C75 treatment of rodent adipocytes and hepatocytes and human breast cancer cells increasesfatty acid oxidation and ATP levels by increasing CPT-1 activity, even in the presence of elevatedconcentrations of malonyl-CoA 4.PROTOCOLCell Assay 1 Cells are seeded in 96-well plates and incub
