Restoring physiological parameters of the pancreas and kidney through treatment with a polymeric nano-formulation of C-peptide and lisofylline combination in diabetic nephropathy.

Diabetic nephropathy (DN) is a progressive kidney disorder that develops as a complication of diabetes due to long-term exposure to elevated blood glucose levels (BGLs). In this case, an intervention of therapeutic moieties is needed to target the specific elements involved in diabetes to prevent/delay the deterioration of kidney function. Therefore, the present study focused on designing and evaluating a potent nano-formulation of a combination of C-peptide (CPep) and the anti-diabetic drug lisofylline (LSF) to prevent streptozotocin (STZ)-induced DN.

Potent anti-inflammatory and anti-apoptotic activities of electrostatically complexed C-peptide nanospheres ameliorate diabetic nephropathy.

In the present era of "Diabetic Pandemic", peptide-based therapies have generated immense interest however, are facing odds due to inevitable limitations like stability, delivery complications and off-target effects. One such promising molecule is C-peptide (CPep, 31 amino acid polypeptide with t 30 min); it is a cleaved subunit of pro-insulin, well known to suppress microvascular complications in kidney but has not been able to undergo translation to the clinic till date. Herein, a polymeric CPep nano-complexes (NPX) was prepared by leveraging electrostatic interaction between in-house synthesized cationic, polyethylene carbonate (PEC) based copolymer (Mol.

Belinostat loaded lipid-polymer hybrid nanoparticulate delivery system for breast cancer: improved pharmacokinetics and biodistribution in a tumor model.

Despite various treatment modalities for breast cancer, it still persists as one of the most diagnosed types of cancer in females. The recent investigations in the epigenetics of breast cancer reveal several aberrations in the expression levels of various HDAC enzymes. Henceforth, the present work entails the formulation and characterization of a lipid polymer-based hybrid nanoparticulate (LPN) system for delivery of an epigenetic modulator drug, Belinostat, for its clinical application in breast cancer.

Role of Chain Length and Degree of Unsaturation of Fatty Acids in the Physicochemical and Pharmacological Behavior of Drug-Fatty Acid Conjugates in Diabetes.

Several drug-fatty acid (FA) prodrugs have been reported to exhibit desirable physicochemical and pharmacological profile; however, comparative beneficial effects rendered by different FAs have not been explored. In the present study, four different FAs (linoleic acid, oleic acid, palmitic acid, and α-lipoic acid) were selected based on their chain length and degree of unsaturation and conjugated to Lisofylline (LSF), an antidiabetic molecule to obtain different drug-FA prodrugs and characterized for molecular weight, hydrophobicity, purity, self-assembly, and efficacy and in type 1 diabetes model. Prodrugs demonstrated a 2- to 6-fold increase in the plasma half-life of LSF.

Therapeutic agents for targeting desmoplasia: current status and emerging trends.

Desmoplasia is a major barrier to chemotherapy in several cancers, particularly pancreatic ductal adenocarcinoma and breast cancer. Tumors comprise of cellular and noncellular components and chemoresistant cancer stem cells (CSCs) with established signaling pathways. In this review, we discuss drugs, such as pentoxifylline, aspirin, and metformin, that have been repurposed and investigated for their antidesmoplastic activity in combination with antitumor drugs.

Multi-component clobetasol-loaded monolithic lipid-polymer hybrid nanoparticles ameliorate imiquimod-induced psoriasis-like skin inflammation in Swiss albino mice.

Lipid-polymer hybrid nanoparticles (LPNs) exhibit several advantages over polymeric and non-polymeric systems in terms of improved drug loading, controlled release, stability, and cellular uptake. Herein we report a scalable and stable monolithic lipid-polymer hybrid nanoparticles (LPNs) consisting of a combination of lipids (solid and liquid) and an amphiphilic copolymer, mPEG-PLA. Clobetasol propionate, a topical corticosteroid, was encapsulated in the hydrophobic core of these LPNs that showed spherical shaped particles with a z-average size of 94.
