Expedient solid-phase synthesis of both symmetric and asymmetric diol libraries targeting aspartic proteases

C2-symmetric diols have been shown to be highly potent against HIV-1 protease (PR). However, gaining access to these compounds has been hampered by the need of multistep solution-phase reactions which are often tedious and inefficient. In this Letter, we have disclosed a solid-phase strategy for rapid preparation of small molecule-based, symmetric and asymmetric diols as potential HIV-1 protease inhibitors. Upon biological screening, we found one of them, SYM-5, to be a potent and selective inhibitor (Ki = 400 nM) against HIV-1 protease.

A novel and efficient synthesis of chiral C2-symmetric 1,4-diamines

A novel and efficient method for synthesis of (R,R)- and (S,S)-C2-symmetric 1,4-diamines was established. The key steps are a combination of Pinacol Coupling and Corey-Winter olefination.

Method for synthesis of C2-symmetric diamino diol mediated by titanium complexes

A method for synthesis of C2-symmetric diamino diol mediated by titanium complexes is provided. A substituted-L-phenylalaninal undergoes pinacol coupling to yield the corresponding C2-symmetric (1S,2R,3R,4S)-1,4-diamino 2,3-diol in the presence of Cp2TiCl2/ZnCl2 and zinc metal, mediated in good yield and highly selective. This titanium-catalyzed reaction yields diaminodiol, offering a convenient alternative method to the synthesis of C2-symmetric peptidic protease inhibitors. Consequently, the method allows to synthesize TL-3 via titanium complex in moderate yield.

Pharmaceutical composition

A solid pharmaceutical composition is disclosed which comprises a pharmaceutically acceptable adsorbent or a mixture of pharmaceutically acceptable adsorbents to which is adsorbed a mixture of (1) a pharmaceutically acceptable organic solvent or a mixture of pharmaceutically acceptable organic solvents, (2) an HIV protease inhibiting compound and (3) one or more pharmaceutically acceptable acids. The solid composition can optionally be encapsulated in a hard gelatin capsule.
