Methods for preparing 2,6-diaryl piperidine derivatives are described. More particularly, 2,6-diaryl piperidines having formula 1-4 are prepared by cyclocondensation of an aryl or heteroaryl aldehyde with 1,3-acetonedicarboxylic acid.

Compounds that interact with the CXCR4 receptor are described. These compounds are useful in treating, for Example, HIV infection and inflammatory conditions such as rheumatoid arthritis, as well as asthma or cancer, and are useful in methods to elevate progenitor and stem cell counts as well as methods to elevate white blood cell counts.

Tumor cells extensively utilize the pentose phosphate pathway for the synthesis of ribose. Transketolase is a key enzyme in this pathway and has been suggested as a target for inhibition in the treatment of cancer. In a pharmacodynamic study, nude mice with xenografted HCT-116 tumors were dosed with 1 ('N3'-pyridyl thiamine'; 3-(6-methyl-2-amino-pyridin-3-ylmethyl)-5-(2-hydroxyethyl)-4-methyl-thiazol-3-ium chloride hydrochloride), an analog of thiamine, the co-factor of transketolase. Transketolase activity was almost completely suppressed in blood, spleen, and tumor cells, but there was little effect on the activity of the other thiamine-utilizing enzymes alpha-ketoglutarate dehydrogenase or glucose-6-phosphate dehydrogenase. Synthesis and SAR of transketolase inhibitors is described. (C) 2007 Elsevier Ltd. All rights reserved.
