Chemotherapy of human immunodeficiency virus (HIV) infection: anti-HIV agents targeted at early stages in the virus replicative cycle

Biomedicine & Pharmacotherapy = Biomédecine & Pharmacothérapie
E De Clercq

Abstract

Several compounds have been identified that inhibit an early stage in the replicative cycle of the human immunodeficiency virus (HIV): i) virus adsorption: polysulfates, polysulfonates, polycarboxylates, polyphosphates, and polyoxometalates; or ii) virus-cell fusion: plant lectins, negatively charged albumins and betulinic acid derivatives; iii) virus fusion/uncoating: bicyclam derivatives; iv) reverse transcription: dideoxynucleoside analogues, acyclic nucleoside phosphonates and non-nucleoside reverse transcriptase inhibitors. In principle, HIV may develop resistance to any of these specific anti-HIV agents. However, virus breakthrough can be completely prevented if these agents, alone or in combination, are added to the HIV-infected cells from the beginning at sufficiently high ('knock-out') concentrations.

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Antivirals (ASM)

Antivirals are medications that are used specifically for treating viral infections. Discover the latest research on antivirals here.
