Finding new chemicals or adjuvants with analgesic effects in the central nervous system is clinically relevant due to the limited number of drugs with these properties. Here, we present PT-31, which is chemically related to 3-benzyl-imidazolidine, with an analgesic profile

We examined the effects of JP-1302 (a selective alpha2C antagonist), BRL-44408 (a selective alpha2A antagonist) and yohimbine (a non-selective alpha2 antagonist) on haloperidol-induced bradykinesia and catalepsy in mice to elucidate the role of alpha2 adrenoceptor subtypes in modifying extrapyramidal motor

Previously, we reported that antinociceptive synergism of a 5-HT(3)/alpha(2)-adrenoceptor ligand MD-354 (m-chlorophenylguanidine) and clonidine combination occurs, in part, through a 5-HT(3) receptor antagonist mechanism. In the present investigation, a possible role for alpha(2)-adrenoceptors was examined. Mechanistic studies using yohimbine (a

The inhibitory effect of clonidine (non-selective alpha2-adrenoceptor agonist) and oxymetazoline (alpha2A-adrenoceptor selective agonist) was compared on basal and stimulated gastric motor activity (gastric tone and contractions) using the balloon method in the rat. It was shown that oxymetazoline (0.2-1.7 micromol/kg
