Chitosan-based porous scaffolds are of great interest in biomedical applications especially in tissue engineering because of their excellent biocompatibility in vivo, good texture, surface contact, controllable degradation rate and tailorable mechanical properties. These days biomaterials scaffolds have contributed as an alternative choice of therapy mainly due to the increase failure rates in autografts and allografts techniques. Terbinafine HCl is allylamines group of drugs which is used topically to treat dermatophyte group of fungi like ringworm. Chitosan possesses both anti-bacterial and antifungal property which synergises with Terbinafine HCl (TBH) for both prophylactic and therapeutic actions in treating fungal wound infection (FWI). The haemostatic property of chitosan allows sorption of plasma, erythrocyte coagulation and platelets activation. These properties contribute additional role in repairing debilitated tissue. The prolong drug release property of fabricated scaffold and its natural characteristics of remodelling tissue favours its use in human fungal wound dressing. The main intention of this research work is to fabricate stable polymer medical devices, examine drug release profile and characterize TBH loaded CS porous scaffold...

The ethanolic extract of Terminalia chebula extract obtained from successive extraction of Rosa damascene by Methanol; n-hexane & n-butanol was subjected to various phytochemical tests. The antioxidant activity was accessed by DPPH method. The anti-Parkinson’s activity was tested in albino Rats. Thirty albino rats (180-250 g) of either sex were divided into five groups and each group consist of six animal (n = 6). Group I: Normal Control (received 0.9% normal Saline) Group II: Disease control (Received Haloperidol 2 mg/kg i.p. single dose for 11 days). Group III: (Received Haloperidol 2 mg/kg i.p. single dose for 11 days) treated with standard drug Levodopa 6 mg/kg p.o continued for the next 45 days. Group IV: (Received Haloperidol 2 mg/kg i.p for 11 days) treated with polyherbal (Terminalia chebula & Rosa damascena) suspension at dose of 100 mg/kg p.o for next 45 days. Group V: (Received Haloperidol 2 mg/kg i.p for 11 days) treated with polyherbal (Terminalia chebula & Rosa damascena) suspension at 200 mg/kg p.o for next 45 days. After...

Three different species of seaweeds collected from south east coast of India such as Sargassum plagiophyllum, Padina gymnospora and Turbinaria conoides for evaluating anti-bacterial activity against selected gram-positive and gram-negative bacteria. Extracts prepared using solvents namely hexane, ethyl acetate, methanol, and water against human pathogenic strains of Proteus vulgaris, Staphylococcus aureus, Klebsiella pneumonia, Enterobacter aerogenes, Salmonella typhimurium, Yersinia pestis, Shigella fiexneri, Staphylococcus epidermidis and Bacillus subtilis. Gram-negative bacteria showed a lesser zone of inhibition than gram-positive bacteria with various extracts tested. All the three solvent extracts of Turbinaria conoides showed, zone of inhibition for the gram-positive bacteria, Staphylococcus epidermidis over the standard control, with a significant zone in hexane extract. Analysis of GC-MS of Turbinaria conoides hexane extract revealed 14 major and numerous minor phytochemical compounds that have to be fractionated and explored for specific anti-bacterial activity in order to isolate a potential anti-bacterial...

Liver fibrosis is a wound healing process that is initiated in response to chronic liver injury caused by viruses, toxins, and hepatotoxic drugs. This disease is characterized by inflammation, followed by the deposition of extracellular matrix proteins to form scar tissue. Ephrin receptor A2 (EphA2) is identified as a host cofactor for Hepatitis C Virus (HCV) entry. The fruits of Solanum nigrum possess anti-inflammatory properties. The present work was done to evaluate the anti-inflammatory activity of the ethanolic fruit extract of Solanum nigrum against EphA2 receptor using Induced fit docking of Schrödinger software. Phyto-compounds were retrieved from the PubChem database. The 3D structure of EphA2 was downloaded from Protein Data Bank (PDB). Among the five phytocompounds, Ethyl caffeate has the Glide Score of -8.01 and glide energy-35.48 kcal/mol. From the results, it is evident that the phytoconstituents of Solanum nigrum fruits have anti-inflammatory potential and prevent hepatic fibrosis. Molecular properties of the compounds were predicted using the Molinspiration tool, and the pharmaco-kinetic properties of the compounds were predicted using...

The current study work is focused on Dapoxetine hydrochloride buccal films. In recent days, buccal drug delivery has aimed at importance in many aspects compared to conventional tablets. The addition of mucoadhesive polymers to the formulation enhances the therapeutic levels of drug. Dapoxetine hydrochloride, a choice of drug used in the therapy of premature ejaculation in men. Dapoxetine hydrochloride is a selective serotonin reuptake inhibitor (SSRI’s) whose oral bioavailability is 42% due to hepatic first-pass metabolism. To enhance the bio-availability and drug release, Dapoxetine hydrochloride is designed as buccal films. They are prepared by the most commonly used solvent-casting method. Two grades of Hypromellose (E15 and 5cps), polyvinyl alcohol, and polyvinyl pyrrolidine are polymers that are mucoadhesive in nature. Propylene glycol is used as a plasticizer, and also mucoadhesive polymer and methanol as a solvent are used in film preparation. FTIR studies were done, and there is no incompatibility between active pharmaceutical ingredient (API) and excipients. The formulations developed were evaluated for different parameters such as weight uniformity, thickness,...
