Multi-drug resistant tuberculosis (MDR-TB) is emerging as a serious global health problem, which has been elevated through co-infection involving HIV and MDR-Mtb. The discovery of new compounds with anti-MDR TB efficacy and favorable metabolism profiles is an important scientific challenge. Using computational biology and ligand docking data, we have… (More)
The 2-position of imidazolium cations is known to be relatively acidic, leading to the useful Arduengo-type carbenes. At the same time, the acidity of this site can lead to undesired side reactions when using imidazolium-based ionic liquids as solvents. In this note, we describe the surprisingly facile deuterium exchange at this position and also the… (More)
[reaction: see text] Fructose has been used as the starting material for the preparation of a new class of room-temperature ionic liquids (RTILs). These liquids exhibit tunable solvent properties much like conventional imidazole-based RTILs. They have been applied as recyclable solvents for the Heck reaction of aryl iodides.
Worldwide research efforts in drug discovery involving HIV integrase have produced only one compound, raltegravir, that has been approved for clinical use in HIV/AIDS. As resistance, toxicity and drug-drug interactions are recurring issues with all classes of anti-HIV drugs, the discovery of novel integrase inhibitors remains a significant scientific… (More)
Research efforts on the human immunodeficiency virus (HIV) integrase have resulted in two approved drugs. However, co-infection of HIV with Mycobacterium tuberculosis and other microbial and viral agents has introduced added complications to this pandemic, requiring favorable drug-drug interaction profiles for antiviral therapeutics targeting HIV.… (More)
[structure: see text] We report a homogeneous supported version of Koser's salt based on a room-temperature ionic liquid (RTIL) support. By altering the nature of the RTIL, a material was developed that was stable, recyclable, and readily separable from the tosyloxylated ketone products just by using variations in solvent polarity. A similar approach should… (More)
HIV integrase, encoded at the 3'-end of the HIV pol gene, is essential for HIV replication. This enzyme catalyzes the incorporation of HIV DNA into human DNA, which represents the point of "no-return" in HIV infection. Integrase is a significant target in anti-HIV drug discovery. This review article focuses largely on the design of integrase inhibitors that… (More)
Integration of viral DNA into human chromosomal DNA catalyzed by HIV integrase represents the "point of no return" in HIV infection. For this reason, HIV integrase is considered a crucial target in the development of new anti-HIV therapeutic agents. We have discovered a novel HIV integrase inhibitor 1, that exhibits potent antiviral activity and a favorable… (More)
Isonucleosides discovered in our laboratory have been found to have interesting antiviral activity. The design, development of methodology, and stereochemical synthesis of new isonucleosides of anti-HCV interest are described. Antiviral results are cited.
The novel HIV-1 integrase inhibitor 1, discovered in our laboratory, exhibits potent anti-HIV activity against a diverse set of HIV-1 isolates and also against HIV-2 and SIV. In addition, this compound displays low cellular cytotoxicity and possesses a favorable in vitro drug interaction profile with respect to isozymes of cytochrome P450 (CYP) and uridine… (More)
