Glucocorticoids are potent anti-inflammatory and immunosuppressant agents. However, they also produce serious side effects that limit their usage. It has been proposed that anti-inflammatory properties of glucocorticoids are caused mostly by repression of activator protein 1- and nuclear factor kappabeta-stimulated synthesis of inflammatory mediators,(More)
The dissociation constants (Kd values) of substance P (SP), physalaemin, kassinin, and SP analogues acting on SP receptors in guinea pig ileal longitudinal muscle strips were determined by the pharmacological procedures of Furchgott [Adv. Drug Res. 3:21-55 (1966)]. This method involves analysis of the concentration-response data before and after fractional(More)
As the incidence of Type II diabetes (T2DM) will increase to 200 million cases worldwide by 2010, the search for new, effective agentsfor its treatment has been pushed into overdrive. According to Unger's bihormonal hypothesis, elevated levels of circulating glucagon in T2DM patients results in increased rates of hepatic glucose synthesis and glycogen(More)
The synthesis and structure-activity relationships of the 4- and 6-substituents of 2,4-diaminopyrimidine-based growth hormone secretagogue receptor (GHS-R) antagonists are described. Diaminopyrimidines with 6-norbornenyl (4n) and 6-tetrahydrofuranyl (4p) substitutents were found to exhibit potent GHS-R antagonism and good selectivity (approximately(More)
