Novel conjugates of endoperoxide and 4-anilinoquinazoline as potential anticancer agents
摘要:
In the present study, endoperoxide and 4-anilinognazoline were conjugated to obtain a series of compounds. These conjugates exhibited high antiproliferative potency against a number of cancer cell lines, including the epidermal growth factor receptor (EGFR) L858R/T790M mutant cell. Compound 5 was selected as a representative for mechanistic study. Further experiments revealed the conjugate's reactive oxygen species (ROS) generating ability, apoptosis inducing activity and involvement in EGFR downstream signaling pathways.

Design and synthesis of bioactive adamantane spiro heterocycles
摘要:
Spiro[aziridine-2,2'-adamantanes] I and 2, spiro[azetidine-2,2'-adamantanes] 3 and 5, spiro[azetidine-3,2'-adamantane] 13, spiro[piperidine-4,2'-adamantanes] 25 and 27, and spiro barbituric analog 18 were synthesized and tested for their anti-influenza A virus properties and for trypanocidal activity. The effect of ring size on potency was investigated. Piperidine 25 showed significant anti-influenza A virus activity, being 12-fold more active than amantadine, about 2-fold more active than rimantadine, and 54-fold more potent than ribavirin. It also proved to be the most active of the compounds tested against bloodstream forms of the African trypanosome, Trypanosoma brucei, being 1.5 times more potent than rimantadine and at least 25 times more active than amantadine.
