Fast and selective synthesis of novel cyclic sulfamide HIV-1 protease inhibitors under controlled microwave heating
摘要:
A novel and highly selective silver-promoted monobenzylation method was developed to promote synthesis of nonsymmetrical sulfamide-based HIV-1 inhibitors. Microwave-accelerated palladium-catalyzed N-amide arylation- and aminocarbonylation reactions were employed for rapid and reliable compound generation. With this class of inhibitory agents, six active inhibitors were identified, the most potent inhibitor possessing a K-i-value of 20 nM. (c) 2006 Elsevier Ltd. All rights reserved.
Cyclic sulfamide HIV-1 protease inhibitors, with sidechains spanning from P2/P2′ to P1/P1′
摘要:
Previous studies of HIV protease inhibitors have shown that it is possible to elongate the P1/P1' sidechains to reach the S3/S3' binding sites. By analogy, We expected that it would be possible to design inhibitors reaching between the S1/S1' and S2/S2' binding sites. Molecular modeling suggested that this could be achieved with appropriate ortho-substitution of the P2/P2' benzyl groups in our cyclic sulfamide inhibitors. Four different spacer groups were investigated. The compounds were smoothly prepared 44 from tartaric acid in five steps and exhibit low to moderate activity, the most potent inhibitor possessing a K-i value of 0.53 muM. (C) 2004 Elsevier Ltd.

A set of 11 non-symmetric cyclic sulfamide HIV-1proteaseinhibitors were synthesized and evaluated. The use of a key microwave-assisted silver(I) oxide mediated selective mono N-benzylation reaction enabled fast and straightforward synthesis. The Ki values of the new inhibitors ranged between 0.28 μM and >20 μM.
