Abstract
With the introduction of antiretroviral therapy, the worldwide AIDS-related deaths have decreased, and life expectancy has increased, including the prevalence of AIDS-related neurological disorders or neuroAIDS. HIV-associated neurocognitive disorders such as mild neurocognitive disorder and asymptomatic neurocognitive impairment have largely remained stable or increased among the HIV-infected individuals in the combination antiretroviral therapy era. The emerging evidence that antiretrovirals with high CNS penetration effectiveness score contribute to the neurotoxicity and HIV-associated neurocognitive disorders has ushered the search for natural, nontoxic bioactive constituents having pre-established neuroprotective, anti-inflammatory, and restorative neurocognitive activity. In this review, we have highlighted the probable mechanism of neuroAIDS infection, the problem with the existing antiretroviral therapy, along with various bioactive constituents with in vivo, in vitro, or ex vivo evidence of their neuroprotective activity that can be used as an adjuvant with the current combination antiretroviral therapy regimen or can even serve as an alternate to the antiretrovirals for treatment of HIV associated neurocognitive disorder.
Keywords: NeuroAIDS, HIV, Dementia, Antiretroviral therapy, Bioactive constituents, Neurocognitive disorders.

Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more
Drug Discovery in the Age of Artificial Intelligence
In the age of artificial intelligence (AI), we have witnessed a significant boom in AI techniques for drug discovery. AI techniques are increasingly integrated and accelerating the drug discovery process. These developments have not only attracted the attention of academia and industry but also raised important questions regarding the selection ...read more
From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
