Novel GlyT1 inhibitor chemotypes by scaffold hopping. Part 2: Development of a [3.3.0]-based series and other piperidine bioisosteres
摘要:
This Letter describes the development and SAR of a novel series of GlyT1 inhibitors derived from a scaffold hopping approach, in lieu of an HTS campaign, which provided intellectual property position. Members within this new [3.3.0]-based series displayed excellent GlyT1 potency, selectivity, free fraction, and modest CNS penetration. Moreover, enantioselective GlyT1 inhibition was observed, within this novel series and a number of other piperidine bioisosteric cores. (C) 2014 Elsevier Ltd. All rights reserved.

Preparation of ketones by insertion of diazo compounds into the formyl C–H bond of an aldehyde is an attractive procedure, but use of structurally diverse diazo compounds is hampered by preparation and safety issues. A convenient procedure for the synthesis of unsymmetrical ketonesfrom bench-stable tosylhydrazones and aryl aldehydes is reported. The procedure can be performed in one pot from the parent

The discovery of a novel series of β-methyltryptophan (β MeTrp) derivatives as selective and orallyactive non-peptide somatostatin receptor 2 (SSTR2) agonists for the treatment of Type 2 diabetes is described. In our previous research, Compound A, β-MeTrp derivative with highly potent and selective SSTR2 agonistic activity IC50 (SSTR2/SSTR5) = 0.3/>100 (nM), was identified as a drug candidate for
Piperidinyl thiacyclic derivatives ##STR1## wherein X, Y, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are defined in the specification. useful in the treatment of allergic diseases and diseases responding to antagonism of 5HT.sub.2 receptors, pharmaceutical compositions and a methods of treatment using these compounds.
