Advances in the treatment of HIV-AIDS with HIV-1 protease inhibitors in combination with reverse transcriptase inhibitors, known as highly active antiretroviral therapy (HAART), has resulted in improved life expectancy and significantly reduced HIV/AIDS-related mortality in the developed world. Unfortunately, HAART suffers from adverse drug side effects, poor oral bioavailability, and drug interactions. In addition, drug-resistant HIV-1 variants have begun to emerge. Development of antiretroviral therapy with broad-spectrum activity and minimal side effects is needed for current and future HIV/AIDS treatment.

Purdue University researchers developed Darunavir, brand name Prezista, a drug used to treat HIV infection. Prezista was developed by the pharmaceutical company Tibotec and is an OARAC recommended treatment option for treatment-naïve and treatment-experienced adults and adolescents. It is also used in patients with drug-resistant HIV.

They have also developed a new generation of protease inhibitors that are exceedingly potent and maintain potency against multidrug resistant HIV-1 variants. Dr. Ghosh's laboratory has designed, synthesized, and evaluated several different series of compounds. These novel protease inhibitors show potent enzyme inhibitory, antiviral activity, and exceptional broad-spectrum activity against highly cross-resistant mutant.

Advantages:
-Decreased adverse side effects
-Effective against multidrug resistant HIV-1 variants
-Improved bioavailability
-Superior pharmacokinetic properties

Potential Applications:
-Medical/Healthcare
-Pharmaceuticals
-Drug Development
-HIV/AIDS Treatment
