De novo design and synthesis of HIV-1 integrase inhibitors
摘要:
Existing AIDS therapies are out of reach for most HIV-infected people in developing countries and, where available, they are limited by their toxicity and their cost. New anti-HIV agents are needed urgently to combat emerging viral resistance and reduce the side effects associated with currently available drugs. Toward this end, LeapFrog, a de novo drug design program was used to design novel, potent, and selective inhibitors of HIV-1 integrase. The designed compounds were synthesized and tested for in vitro inhibition of HIV-1 integrase. Out of the 25 compounds that were designed, and synthesized, four molecules (compounds 23, 26, 43, and 59) showed moderate to low inhibition of HIV-1 integrase for 3'-processing and 3'-strand transfer activities. Nonetheless, these compounds possess structural features not seen in known HIV-1 integrase inhibitors and thus can serve as excellent leads for further optimization of anti-HIV-1 integrase activity.

useful carbamoyl fluorides. High selectivity for fragmentation over a potentially competing Beckmann rearrangement was observed. This protocol has a distinct mechanism and thus a different substrate scope compared with other synthetic methods. α-Oximinoamides derived from the readily available secondary amines, lactams, or isatins were converted into structurally diverse carbamoyl fluorides.

N-[(aminosulfonyl)phenyl]-2-(1,2-dihydro-2-oxo-3H-indol-3-ylidene)-hydrazinecarbothioamide derivatives of the following formula (III) for treating cancer and immunological disorders. R5, R6 and R7 are each independently selected from hydrogen and a sulfonamide group, provided that at least one of R5, R6 or R7 is a sulfonamide group. The substituents R1 to R4 are each independently either hydrogen or one of the substituents defined in the claims.
