In order to search for new antitumor drugs with high efficiency and low toxicity, a series of novel 4-aminoquinazoline derivatives containing 1,3,4-thiadiazole group were designed, synthesized evaluated antiproliferative activity against four human cancer cell lines (H1975, PC-3, MCF-7 HGC-27) using MTT assay in vitro. Among them, compound N-(5-((3,5-dichlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)-...

The subject of this thesis is the development of a potentially simple, general and economical synthetic protocol for the potent antimalarial alkaloid febrifugine (1) and its analogues. In Chapter 1, the interesting history of 1, which includes a description of several reported total syntheses of 1, is discussed. Natural products derived from 1, as well as promising synthetic derivatives that di...
