A series of 2-(3,5-substituted 4-aminophenyl)acetamide and propanamide derivatives were investigated as human TRPV1 antagonists. The analysis of the structure-activity relationship indicated that 2-(3,5-dihalo 4-aminophenyl)acetamide analogues displayed excellent antagonism of hTRPV1 activation by
Capsaicin, the active ingredient in some pain-relieving creams, is an agonist of a nonselective cation channel known as the transient receptor potential vanilloid type 1 (TRPV1). The pain-relieving mechanism of capsaicin includes desensitization of the channel, suggesting that TRPV1 antagonism may

Introduction: Chloramphenicol (2,2-dichloro-N-[1,3-dihydroxy-1-(4-nitrophenyl)porpan-2-yl]acetamide) is a bacteriostatic antibiotic of the phenicolated family, used in the past to treat meningitis, plague, cholera, or typhoid fever. Treatment with chloramphenicol can have life threatening
The amino (N)-terminal and central regions of the ryanodine receptor (RyR) containing most mutation sites of malignant hyperthermia (MH) and central core disease (CCD) seem to be involved in the Ca(2+) channel regulation. Our recent peptide probe study (Yamamoto, T., El-Hayek, R., and Ikemoto, N.
We have investigated the roles of peripheral and central mu, delta, and kappa opioid receptors and their subtypes in opioid-induced hypothermia in mice. Measuring rectal temperature after i.p. injection, opioid agonists [morphine, fentanyl, SNC80
Colchicine, an antimitotic alkaloid isolated from Colchicum autumnale, is a classical drug for treatment of gout and familial Mediterranean fever. It causes antiproliferative effects through the inhibition of microtubule formation, which leads to mitotic arrest and cell death by apoptosis. Here, we
