Lopinavir (ABT-378) is an antiretroviral of the protease inhibitor class. It is used against HIV infections as a fixed-dose combination with another protease inhibitor, ritonavir, under the trade names Kaletra.

Nelfinavir is a protease inhibitor with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Protease inhibitors block the part of HIV called protease. HIV-1 protease is an enzyme required for the proteolytic cleavage of the viral polyprotein precursors into the individual functional proteins found in infectious HIV-1. Nelfinavir binds to the protease active site and inhibits the activity of the enzyme. This inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature non-infectious viral particles. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs. Nelfinavir inhibits the HIV viral proteinase enzyme which prevents cleavage of the gag-pol polyprotein, resulting in noninfectious, immature viral particles. Nelfinavir is used in combination with other antiviral drugs in the treatment of HIV in both adults and children. Nelfinavir is marketed under the brand name Viracept.

Terconazole is an antifungal drug used to treat vaginal yeast infection. Terconazole may exert its antifungal activity by disrupting normal fungal cell membrane permeability. Terconazole and other triazole antifungal agents inhibit cytochrome P450 "14-alpha-demethylase" in susceptible fungi, which leads to the accumulation of lanosterol and other methylated sterols and a decrease in ergosterol concentration. Depletion of ergosterol in the membrane disrupts the structure and function of the fungal cell leading to a decrease or inhibition of fungal growth. During controlled clinical studies conducted in the United States, 521 patients with vulvovaginal candidiasis were treated with terconazole 0.4% vaginal cream. Based on comparative analyses with placebo, the adverse experiences considered most likely related to terconazole 0.4% vaginal cream were a headache and body pain. Fever and chills, vulvovaginal burning, itching, and irritation have also been reported. The adverse drug experience on terconazole most frequently causing discontinuation was vulvovaginal itching.

Bathocuproine is a promising organic material of a hole blocking layer in organic light-emitting diodes or an electron buffer layer in organic photovoltaic cells. When a thin layer of bathocuproine is inserted between the metal electrode and the organic layer of the organic semiconductor device, the electron injection/collection efficiency at the interface is significantly improved. As an organic electronic material bathocuproine useful as OLED electron transporter and hole blocker. Bathocuproine sulphonate acts as a specific chelator of monovalent copper Cu(I).

Arno Therapeutics is developing AR-12, an orally available, targeted therapy for cancer and infectious diseases. AR-12 is a potentially first-in-class, orally available, targeted anti-cancer agent that has been shown in preclinical studies to inhibit phosphoinositide-dependent protein kinase-1, or PDK-1, a protein in the PI3K/Akt pathway that is involved in the growth and proliferation of cells, including cancer cells. Although FDA-approved drugs that target the Akt pathway have shown efficacy in treating cancer, some tumors either do not respond to these drugs or eventually become resistant to therapy. Scientists hypothesize that a combination of drugs that inhibit different targets in this pathway could provide synergistic or additive benefits to increase efficacy and potentially overcome drug resistance. For this reason, there has been particular interest within the biopharmaceutical industry in developing inhibitors of PI3K, PDK-1, and Akt. AR-12 was licensed to Arno in January 2008 by The Ohio State University Research Foundation for commercial development by Arno as a potential treatment for solid tumors and hematological malignancies. In preclinical studies, AR-12 has shown efficacy in a wide range of tumor types, including breast, lung, prostate, pancreatic, brain and hematological cancers, as both a single-agent as well as in combination with leading oncology therapeutics. Also AR-12 represents a promising class of small molecules with broad-spectrum antifungal activity. AR-12 inhibits fungal acetyl coenzyme A (acetyl-CoA) synthetase in vitro and is fungicidal at concentrations similar to those achieved in human plasma. AR-12 has a broad spectrum of activity, including activity against yeasts (e.g., Candida albicans, non-albicans Candida spp., Cryptococcus neoformans), molds (e.g., Fusarium, Mucor), and dimorphic fungi (Blastomyces, Histoplasma, and Coccidioides) with MICs of 2 to 4 ug/ml. AR-12 is also active against azole- and echinocandin-resistant Candida isolates, and subinhibitory AR-12 concentrations increase the susceptibility of fluconazole- and echinocandin-resistant Candida isolates. Also AR-12 acts as a broad-specificity anti-viral drug in vitro and in vivo. AR-12 (OSU-03012) interacts with multiple chaperone proteins of the HSP90 family and the HSP70 family resulting in a broad spectrum of chaperone inactivation. This overall loss of chaperone functionality results in cells being more readily capable of undergoing autophagic processes and in cells that have a reduced competency for virus replication.

TAK-779 is a selective antagonist of CCR5 receptor, which was initially developed by Takeda for the treatment of HIV infection. However, the development was terminated due to poor oral bioavailability. Also, TAK-779 demonstrated the ability to protect the brain against focal cerebral ischemia in mice.

Epicatechin-5-Sulfate is a metabolite of epicatechin. It is patented for inclusion in food formulations intended for weight loss, and treatment of diabetes.

Indinavir is an antiretroviral drug for the treatment of HIV infection. Indinavir is a protease inhibitor with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Protease inhibitors block the part of HIV called protease. HIV-1 protease is an enzyme required for the proteolytic cleavage of the viral polyprotein precursors into the individual functional proteins found in infectious HIV-1. Indinavir binds to the protease active site and inhibits the activity of the enzyme. This inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature non-infectious viral particles. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs.

Saquinavir (brand names Invirase and Fortovase) is an antiretroviral drug used together with other medications to treat or prevent HIV/AIDS. Saquinavir is an inhibitor of HIV protease. HIV protease is an enzyme required for the proteolytic cleavage of viral polyprotein precursors into individual functional proteins found in infectious HIV. Saquinavir is a peptide-like substrate analog that binds to the protease active site and inhibits the activity of the enzyme. Saquinavir inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature noninfectious virus particles. The most frequent adverse events with saquinavir in either formulation are mild gastrointestinal symptoms, including diarrhea, nausea, loose stools & abdominal discomfort. Invirase is better tolerated than Fortovase.

The nucleoside analog 2',3'-dideoxycytidine (ddCyd), also known as Zalcitabine is a nucleoside analog reverse transcriptase inhibitor (NRTI) sold under the trade name Hivid. HIVID is indicated in combination with antiretroviral agents for the treatment of HIV infection. It is used as part of a combination regimen with antiretroviral agents. But it was discontinued by Roche Pharmaceuticals on December 31, 2006 due to the availability of newer HIV medicines. Within cells, zalcitabine is converted to the active metabolite, dideoxycytidine 5'-triphosphate (ddCTP), by the sequential action of cellular enzymes. Dideoxycytidine 5'-triphosphate inhibits the activity of the HIV-reverse transcriptase both by competing for utilization of the natural substrate, deoxycytidine 5'-triphosphate (dCTP), and by its incorporation into viral DNA. The lack of a 3'- OH group in the incorporated nucleoside analogue prevents the formation of the 5' to 3' phosphodiester linkage essential for DNA chain elongation and, therefore, the viral DNA growth is terminated. The active metabolite, ddCTP, is also an inhibitor of cellular DNA polymerasebeta and mitochondrial DNA polymerase-gamma and has been reported to be incorporated into the DNA of cells in culture.
