HIV Vaccine for Prevention and Cure, A Mission Possible.

HIV/AIDS was once a highly deadly infective disease that killed the global people of a million annually two decades ago. While we are enjoying the HIV therapeutic advances (mostly important from HAART invention), one obvious drawback is still unresolved-unable to clearance all HIV from infected human bodies. As a result, a series of different therapeutic attempts have been proposed based on present knowledge of different features of HIV-induced pathogenesis and human mortalities.

Synthesis, structure activity relationship and mode of action of 3-substitutedphenyl-1-(2,2,8,8-tetramethyl-3,4,9,10-tetrahydro-2H,8H-pyrano[2,3-f]chromen-6-yl)-propenones as novel anticancer agents in human leukaemia HL-60 cells.

A novel class of 3-substitutedphenyl-1-(2,2,8,8-tetramethyl-3,4,9,10-tetrahydro-2H,8H-pyrano[2,3-f]chromen-6-yl)-propenones were designed, synthesized and evaluated for their antiproliferative activity against the human cancer cell lines of diverse origin. Structure activity relationship was elucidated with various substitutions on the benzene ring and these variations significantly affected the potency. Most of the twelve tested compounds inhibited the growth of aggressive cancer cell lines.
