Advanced drug delivery and therapeutic strategies for tuberculosis treatment.

Tuberculosis (TB) remains a significant global health challenge, necessitating innovative approaches for effective treatment. Conventional TB therapy encounters several limitations, including extended treatment duration, drug resistance, patient noncompliance, poor bioavailability, and suboptimal targeting. Advanced drug delivery strategies have emerged as a promising approach to address these challenges.

Repurposing Vorinostat for the Treatment of Disorders Affecting Brain.

Based on the findings in recent years, we summarize the therapeutic potential of vorinostat (VOR), the first approved histone deacetylase (HDAC) inhibitor, in disorders of brain, and strategies to improve drug efficacy and reduce side effects. Scientific evidences provide a strong case for the therapeutic utility of VOR in various disorders affecting brain, including stroke, Alzheimer's disease, frontotemporal dementia, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, spinal muscular atrophy, X-linked adrenoleukodystrophy, epilepsy, Niemann-Pick type C disease, and neuropsychiatric disorders. Further elucidation of the neuroprotective and neurorestorative properties of VOR using proper clinical study designs could provide momentum towards its clinical application.

Rapid acting antidepressants in the mTOR pathway: Current evidence.

Despite the growing burden of major depressive disorder (MDD) on the society, therapeutic management that is mostly based on the conventional monoaminergic mechanisms, is significantly delimited especially from low response rate and time lag for treatment response; thus, often prolonging the distress for patients. The mechanistic exploration of drug candidates that could exert antidepressant effects rapidly has highlighted the significance of modulating mammalian target of rapamycin (mTOR) pathway in MDD. Fast acting antidepressants acts at different receptors, subunits and sites, including NMDA, AMPA, m1ACh, mGluR2/3 and GluN2B to enhance mTOR function, leading to increase in synaptic protein synthesis, synaptogenesis and spine-remodeling, which in turn contribute to the rapid antidepressant effects.

Cognitive Improvement by Vorinostat through Modulation of Endoplasmic Reticulum Stress in a Corticosterone-Induced Chronic Stress Model in Mice.

Chronic stress is the leading cause of memory impairment today. Various stress-based models are being developed for studying cognitive impairment. Repurposing of existing drugs in a new pharmacology class is the safest and cheapest option for treatment instead of new drug discovery.

An Overview of the Heterogeneity of Major Depressive Disorder: Current Knowledge and Future Prospective.

Major depressive disorder (MDD) is estimated to impose maximum debilitating effects on the society by 2030, with its critical effects on health, functioning, quality of life and concomitant high levels of morbidity and mortality. Yet, the disease is inadequately understood, diagnosed and treated. Moreover, with the recent drastic rise in the pace of life, stress has materialized as one of the most potent environmental factors for depression.

Morin Hydrate Mitigates Cisplatin-Induced Renal and Hepatic Injury by Impeding Oxidative/Nitrosative Stress and Inflammation in Mice.

Cisplatin is a widely used chemotherapeutic drug; however, it induces damage on kidney and liver at clinically effective higher doses. Morin hydrate possesses antioxidant, anti-inflammatory, and anticancer properties. Therefore, we aimed to investigate the effects of morin hydrate (50 and 100 mg/kg, orally) against the renohepatic toxicity induced by a high dose of cisplatin (20 mg/kg, intraperitoneally).

Flavonoids, the emerging dietary supplement against cisplatin-induced nephrotoxicity.

The letter illustrates the emerging potential of flavonoids as dietary supplement to ameliorate cisplatin-induced nephrotoxicity and refers to the recent article on ''Anti-apoptotic and anti-inflammatory effects of naringin on cisplatin-induced renal injury in the rat'' by Chtourou et al. They demonstrated that supplementation of naringin, a flavanone glycoside, found in grape and citrus fruit species, can attenuate cisplatin-induced renal dysfunction via restoration of redox balance and suppression of inflammation, NF-κB activation and apoptosis. The chemotherapeutic efficacy of cisplatin has always compelled the researchers to find solution to ameliorate its side effects.

Alternative mechanisms of inhibiting activity of poly (ADP-ribose) polymerase-1.

Poly ADP-ribose polymerase (PARP-1), a DNA nick-sensor enzyme, is an abundant nuclear protein. Upon sensing DNA breaks, PARP-1 gets activated and cleaves NAD into nicotinamide and ADP-ribose and polymerizes the latter onto nuclear acceptor proteins including histones, transcription factors, and PARP-1 itself. Poly(ADP-ribosylation) mainly contributes to DNA repairing mechanism.

Resveratrol ameliorates depressive-like behavior in repeated corticosterone-induced depression in mice.

A mouse model of depression has been recently developed by exogenous corticosterone (CORT) administration, which has shown to mimic HPA-axis induced depression-like state in animals. The present study aimed to examine the antidepressant-like effect and the possible mechanisms of resveratrol, a naturally occurring polyphenol of phytoalexin family, on depressive-like behavior induced by repeated corticosterone injections in mice. Mice were injected subcutaneously (s.

Chemopreventive and therapeutic potential of chrysin in cancer: mechanistic perspectives.

Chrysin, a naturally occurring flavone, abundantly found in numerous plant extracts including propolis and in honey is one of the most widely used herbal medicine in Asian countries. Nowadays, chrysin has become the foremost candidate exhibiting health benefits, owing to its multiple bioactivities such as antioxidant, anti-inflammatory, anti-allergic, anti-diabetic, anti-estrogenic, antibacterial and antitumor activities. Anticancer activity is most promising among the multiple pharmacological effects displayed by chrysin.
