Development and testing of nanoparticles delivery for P7C3 small molecule using injury models.

The use of nanoparticles (NPs) has emerged as a potential tool for safe and effective drug delivery. In the present study, we developed small molecule P7C3-based NPs and tested its efficacy and toxicity along with the tissue specific aptamer-modified P7C3 NPs. The P7C3 NPs were prepared using poly (D, L-lactic-co-glycolic acid) carboxylic acid (PLGA-COOH) polymer, were conjugated with skeletal muscle-specific RNA aptamer (A01B P7C3 NPs) and characterized for its cytotoxicity, cellular uptake, and wound healing in vitro.

Cardioprotective Effects of 1-(3,6-Dibromo-carbazol-9-yl)-3-Phenylamino-Propan-2-Ol in Diabetic Hearts via Nicotinamide Phosphoribosyltransferase Activation.

Diabetes is associated with increased cardiac injury and sudden death. Nicotinamide phosphoribosyltransferase (Nampt) is an essential enzyme for the NAD salvage pathway and is dysregulated in diabetes. Nampt activation results in rescued NADH/NAD ratios and provides pharmacological changes necessary for diabetic cardioprotection.

Nampt activator P7C3 ameliorates diabetes and improves skeletal muscle function modulating cell metabolism and lipid mediators.

Background: Nicotinamide phosphoribosyltransferase (Nampt), a key enzyme in NAD salvage pathway is decreased in metabolic diseases, and its precise role in skeletal muscle function is not known. We tested the hypothesis, Nampt activation by P7C3 (3,6-dibromo-α-[(phenylamino)methyl]-9H-carbazol-9-ethanol) ameliorates diabetes and muscle function.

Methods: We assessed the functional, morphometric, biochemical, and molecular effects of P7C3 treatment in skeletal muscle of type 2 diabetic (db/db) mice.

Alzheimer's disease and sleep disorders: Insights into the possible disease connections and the potential therapeutic targets.

One of the comorbid conditions in an individual with Alzheimer's disease is a sleep disorder. Clinical features of sleep disorders involve various sleep disturbances such as Obstructive Sleep Apnea (OSAS), Excessive Daytime Sleepiness (EDS), Rapid Eye Movement (REM), Breathing Disorders, Periodic limb movements in sleep (PLMS), etc. The primary tools used for the identification of such disturbances are Polysomnography (PSG) and Wrist actigraphy.
