Roscovitine and CR8 are potent inhibitors of cyclin-dependent kinases. A scalable synthesis of both inhibitors is described. In the case of CR8, the biarylmethylamine moiety was obtained as a stable and high-purity salt.
Bradykinin B1 antagonists: SAR studies in the 2,3-diaminopyridine series
摘要:
SAR study of the biphenyl region of 2,3-diaminopyridine bradykinin B-1 antagonists was investigated with non-aromatic carbo- and heterocyclic rings. A piperidine ring was found to be a good replacement for the proximal phenyl ring while replacement of the distal phenyl was optimal with a cyclohexyl group leading to a dramatic improvement in affinity for the B-1 receptor.
