Synthesis and biological evaluation of gemcitabine–lipid conjugate (NEO6002)
摘要:
A novel gemcitabine-lipid conjugate 5 was synthesized and tested for its in vivo efficacy and toxicity. Compound 5 was tested in BxPC-3 human pancreatic tumor model in SCID mice and exhibited promising activity and lower toxicity when compared with Gerrizar (R). (c) 2005 Elsevier Ltd.

Inhibition of human erythrocyte membrane phosphatidylinositol 4-kinase by phospholipid analogues
Analogues of phosphatidylinositol (Ptdlns, 1) have been synthesized to investigate the structural requirements for inhibition of a Ptdlns 4-kinase obtained from human erythrocyte membranes. While the presence of either D-1 or D-3 Stereochemistry in the inositol moiety greatly influences the degree of inhibition produced by Ptdlns analogues, the stereochemistry of the glycerol moiety is of little consequence. Neither structural feature, however, makes a significant contribution to binding affinity. Competitive inhibitory activity was found to be retained (or even enhanced) in substantially simpler analogues consisting of 1 or 2 hydrocarbon chains attached to a charged phosphate head group, such as in the phosphatidic acids, 24 and 26. The observation that the phosphatidylinositol 4-phosphate (Ptdlns 4P) and phosphatidic acid analogues (eg, 16 or 17, and 26 respectively) inhibit Ptdlns 4-kinase may suggest that such species have a regulatory role in Ptdlns turnover.
