The invention is directed to substituted pyridine derivatives. Specifically, the invention is directed to compounds according to Formula (Iar):
wherein Yar, X1ar, X2ar, R1ar, R2ar, R3ar, R4ar and R5ar are as defined herein; or a pharmaceutically acceptable salt or prodrug thereof.
The compounds of the invention are selective inhibitors of DNMT1 and can be useful in the treatment of cancer, pre-cancerous syndromes, beta hemoglobinopathy disorders, sickle cell disease, sickle cell anemia, and beta thalassemia, and diseases associated with DNMT1 inhibition. Accordingly, the invention is further directed to pharmaceutical compositions comprising a compound of the invention. The invention is still further directed to methods of inhibiting DNMT1 activity and treatment of disorders associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.
Synthesis of Oxacalixarenes Incorporating Nitrogen Heterocycles: Evidence for Thermodynamic Control

日期:2006.6.1
Oxacalix[2]arene[2] hetarenes are formed in a single step by cyclooligomerization of meta-diphenols with meta-dichlorinated azaheterocycles. The high selectivity for cyclic tetramer formation results from thermodynamic product control. Macrocycles as large as oxacalix[5] arene[5]hetarenes have been isolated under nonequilibrating conditions.

日期:2005.8.1
Bicyclooxacalixarenes are obtained in up to 95% yield by condensation of phloroglucinol with electron-poor meta-dihalogenated benzenes or pyridines. Single-crystal X-ray analysis reveals that these compounds adopt highly symmetrical, all-1,3-alternate cage-like structures.
