Inspired by our previous efforts to improve the drug-resistance profiles of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs), a novel series “dual-site” binding diarylpyrimidine (DAPY) derivatives targeting both NNRTI adjacent site and NNRTIs pocket (NNIBP) were designed, synthesized, evaluated for their anti-HIV potency in TZM-bl MT-4 cells. Eight compounds exhibited moderate exc...

Background Toxicities due to anti-TB treatment frequently occur among TB/HIV-coinfected patients. Objectives To determine the association between anti-TB drug concentrations and the occurrence of hepatotoxicity and peripheral neuropathy among TB/HIV-coinfected patients. Methods TB/HIV-coinfected patients were started on standard dose anti-TB treatment according to WHO guidelines. Anti-TB dr...

Despite the wide variety of highly potent anti-HIV drugs that have been developed and made available in clinical practice over the years, eradication of HIV infection has not been achieved. Currently, HIV infection and AIDS are thought to be chronically treatable. HIV attacks host immune cells namely macrophages and CD4(+)T-cells and sequesters itself into sanctuary and reservoir sites such as ...

Despite modern prevention and treatment strategies, human cytomegalovirus (HCMV) remains a common opportunistic pathogen associated with serious morbidity and mortality in immunocompromised individuals, such as transplant recipients and AIDS patients. All drugs currently licensed for the treatment of HCMV infection target the viral DNA polymerase and are associated with severe toxicity issues a...

background: evidences show that aloe vera (a. vera), camellia sinensis, hibiscus sabdariffa and sophora alopecuroides may prevent gastric ulcer induced by non-steroidal anti-inflammatory drugs (nsaids). objective: to examine the protective potential of these plants against indomethacin-induced gastric ulcer in the rat. methods: saline, a. vera leaf gel powder and 70% alcoholic extracts of the o...

  Background and Objectives: Toxoplasmosis has become one of the more frequent opportunistic infections and the most common cause of focal brain lesions complicating the course of AIDS. However, there is a little information about the frequency of the toxoplasmosis in various regions of Iran. At the present study, we evaluated the prevalence of toxoplasmosis in patients with AIDS in Mashhasd (...

BACKGROUND HIV-HBV-coinfected individuals who need to be treated only for their HBV infection have limited therapeutic options, since most approved anti-HBV agents have a risk of selecting for drug-resistant HIV mutants. In vivo data are inconclusive as to whether telbivudine (LdT) may exert antiviral effects against HIV. Thus, we investigated in further detail the antiviral activity and the bi...

BACKGROUND Multidrug resistant and extensively drug resistant tuberculosis (TB) have become major threats to control of tuberculosis globally. The rates of anti-TB drug resistance in Uganda are not known. We conducted a national drug resistance survey to investigate the levels and patterns of resistance to first and second line anti-TB drugs among new and previously treated sputum smear-positiv...

From 1992 to 1995 we studied 232 (69% male, 87% Caucasian) anti-human immunodeficiency virus (anti-HIV) positive Brazilian patients, through a questionnaire; HIV had been acquired sexually by 50%, from blood by 32%, sexually and/or from blood by 16.4% and by an unknown route by 1.7%. Intravenous drug use was reported by 29%; it was the most important risk factor for HIV transmission. The alanin...

We designed, synthesized, and identified JE-2147, an allophenylnorstatine-containing dipeptide HIV protease inhibitor (PI), which is potent against a wide spectrum of HIV-1, HIV-2, simian immunodeficiency virus, and various clinical HIV-1 strains in vitro. Drug-resistant clinical HIV-1 strains, isolated from seven patients who had failed 9-11 different anti-HIV therapeutics after 32-83 months, ...
