active inhibitor of histone deacetylases (HDACs) in clinical trials for multiple myeloma, leukemia, and lymphoma. It has few hydrogen bond donors and acceptors but is a chiral 2-arylbutyrate and potentially prone to racemization. We report achiral AR-42 analogues incorporating a cycloalkyl group linked via a quaternary carbon atom, with up to 40-fold increased potency against human class I HDACs (e

Numerous potent P2X3 antagonists have been discovered and the therapeutic potential of P2X3 antagonism already comprises proof-of-concept data obtained in clinical trials with the most advanced compound. We have lately reported the discovery and optimization of thia-triaza-tricycle compounds with potent P2X3 antagonistic properties. This Letter describes the SAR of a back-up series containing a 4-oxo-quinazoline

S1P1 agonists. We have recently disclosed a series of orallyactive tetrahydroisoquinoline (THIQ) compounds matching these criteria. In this paper we describe how we defined and implemented a strategy aiming at the discovery of selective structurally distinct follow-up agonists. This effort culminated with the identification of a series of orallyactive tetrahydropyrazolopyridines.
