Conformation-activity relationship study of 5-HT3 receptor antagonists and a definition of a model for this receptor site
摘要:
A conformation-activity relationship study of 5-HT3 receptor antagonists was used to define a pharmacophore and receptor map to qualitatively account for their activity. The design and synthesis of specific keto-amino-indole derivatives that are potent 5-HT3 receptor antagonists gave some support to the model.

fluorous variants of the Boc (tert-butyloxycarbonyl) group have been prepared and tested for their suitability as nitrogen protecting groups. A group with two fluorous chains and an ethylene spacer, (RfCH2CH2)2(CH3)COC(O)-, was readily attached to a representative amine but was difficult to cleave. In contrast, groups with two fluorous chains and a propylene spacer, (RfCH2CH2CH2)2(CH3)COC(O)-, or one fluorous

Disclosed are substituted tricyclic benzimidazoles compounds as defined herein in formula (I) or pharmaceutically acceptable salts thereof. The compounds of the invention selectively inhibit CDK8 and are therefore useful for treating diseases related to this kinase, especially colorectal and melanoma cancers and other solid and hemathological malignancies, autoimmune diseases and inflammatory diseases. Also disclosed are processes for preparing these compounds.

1-Aminopyridinium ylides are efficientdirecting groups for palladium-catalyzed β-arylation and alkylation of sp3 C-H bonds in carboxylic acid derivatives. The efficiency of these directing groups depends on the substitution at the pyridine moiety. The unsubstituted pyridine-derived ylides allow functionalization of primary C-H bonds, while methylene groups are unreactive in the absence of external
PdII‐catalyzed C(sp3)−Harylation of saturatedheterocycles with a wide range of aryl iodides is enabled by an N‐heterocyclic carbene (NHC) ligand. A C(sp3)−H insertion step by the PdII/NHC complex in the absence of ArI is demonstrated experimentally for the first time. Experimental data suggests that the previously established NHC‐mediated Pd0/PdII catalytic manifold does not operate in this reaction
