Discovery of Dual Targeting GSK-3β/HIV-1 Reverse Transcriptase Inhibitors as Neuroprotective Antiviral Agents.

Glycogen synthase kinase-3 beta (GSK-3β or GSK-3B) is a serine-threonine kinase involved in various pathways and cellular processes. Alteration in GSK-3β activity is associated with several neurological diseases including Alzheimer's disease (AD), bipolar disorder, and rare diseases like Rett syndrome. GSK-3β is also implicated in HIV-associated dementia (HAD), as it is upregulated in HIV-1-infected cells and plays a role in neuronal dysfunction.

Real-time evaluation of macozinone activity against through bacterial nanomotion analysis.

Novel drugs and improved diagnostics for (MTB) are urgently needed and go hand in hand. We evaluated the activity of two benzothiazinone drug candidates (MCZ, PBTZ169; BTZ043) and their main metabolites against MTB using advanced nanomotion technology. The results demonstrated significant reductions in MTB viability within 7 h, indicating the potential for rapid, precise antibiotic susceptibility testing based on a phenotypic read-out in real time.

Nitric oxide induces the distinct invisibility phenotype of Mycobacterium tuberculosis.

During infection Mycobacterium tuberculosis (Mtb) forms physiologically distinct subpopulations that are recalcitrant to treatment and undetectable using standard diagnostics. These difficult to culture or differentially culturable (DC) Mtb are revealed in liquid media, their revival is often stimulated by resuscitation-promoting factors (Rpf) and prevented by Rpf inhibitors. Here, we investigated the role of nitric oxide (NO) in promoting the DC phenotype.

Dynamic features of virus protein 1 and substitutions in the 3-phenyl ring determine the potency and broad-spectrum activity of capsid-binding pyrazolo[3,4-d]pyrimidines against rhinoviruses.

Pyrazolo[3,4-d]pyrimidines represent one potent class of well tolerated and highly active rhinovirus (RV) inhibitors that act as capsid binders. The lead compound OBR-5-340 inhibits a broad-spectrum of RVs. Aiming to improve lead activity, we evaluated the impact of structural modifications in the 3-phenyl ring of OBR-5-340 on its potency and spectrum of anti-RV activity vitro.

The novel drug candidate VOMG kills Mycobacterium abscessus and other pathogens by inhibiting cell division.

Aims: The incidence of lung infections is increasing worldwide in individuals suffering from cystic fibrosis and chronic obstructive pulmonary disease. Mycobacterium abscessus is associated with chronic lung deterioration in these populations. The intrinsic resistance of M.
