Aeromonas hydrophila is a gram negative bacterium which is primary or secondary cause of ulcers and hemorrhagic septicaemia in fish. The treatments for this infection are only restricted to some antibiotics. So, novel materials are being searched for combating with bacterial infections and the resulting consequences. In this presence study, the green synthesized silver nanoparticles using Hibiscus rosa sinensis extract act as reducing agent. The silver nanoparticles have shown bactericidal effects against A. hydrophila isolated from infected fish Catla catla. The silver nanoparticles were characterized by using UV–Visible, fourier transform infra-red spectroscopy (FT-IR) and scanning electron microscopy (SEM) techniques. SEM results showed that the particles were in the size range of 5µm. FT-IR prediction indicated the presence of C–H stretch, C–H bend, N–H bend, –C≡C– stretch, H–C=O: C–H stretch, C–H stretch respectively on the AgNPs. The maximum zone of inhibition 10 mm observed by normal cured against A. hydrophila is. The synthesized silver nanoparticles exhibited maximum zone of inhibition 11 mm against A. hydrophila. As a conclusion of the...

Globally at present, there are an estimated 366 million people affected with diabetes mellitus. The Indian figure is around 61.3 million diabetics, which is projected to cross 100 million by the year 2030. Owing to rise of diabetes mellitus cases, the economic burden due to diabetes in India ranks the highest in the world. With the increasing prevalence of diabetes, it has resulted in an increase in its complications which has resulted in increasing morbidity, mortality and health expenditure due to the requirement of specialized care. Diabetes Mellitus is one of the most prevalent chronic disorders in the modern world. CRP is a plasma protein which is not normally present in the body but its advent is marked by its elevated levels in the blood during certain specific condition, especially marked during the inflammatory events occurred as a result of any kind of injury. Due to its involvement in inflammation, which is also seen as one of the mediators of progression of type II diabetes mellitus and its various...

The present study aims to synthesize highly stable and dispersed cytotoxic silver nanoparticles (AgNPs) from Tabernaemontana divaricata (T. divaricata) leaves extract, by using noble green approach at room temperature. Phytocomponents were investigated using general methods and found good agreement with reported literature. Green synthesized AgNPs were characterized using UV-Vis, FT-IR, XRD, TGA, FEG-SEM, EDX, TEM, SAED and AFM spectroscopy techniques. XRD and SEAD confirmed polycrystalline nature. TEM study shows spherical morphology with size range 6-20 nm. Suforhodamine B (SRB) assay revealed potent cytotoxicity of AgNPs on A549 cells with IC50 value 32.3µg/ml. As per SRB assay in case of AgNPs, GI50 = 37.1µg/ml, TGI = 68.9µg/ml, LC50 = > 80µg/ml, while T. divaricata exhibits GI50, TGI, LC50 values = > 80µg/ml, indicating greater biocompatibility of AgNPs in comparison to T. divaricata leaves extract. This investigation reveals that T. divaricata mediated AgNPs has a great potential for the development of an efficient anticancer nano drug with minimal side effects to combat against life-threatening lung...

Present studies describe the synthesis of a series of Schiff base derived quinazolinone derivatives (6-14) with the aim to have better anti inflammatory agents. The prepared compounds were characterized using chemical and spectral (IR, NMR and Mass) studies. Pharmacological evaluation of the newly synthesized derivatives indicated that compounds 8, 11 and 14 exhibit significant anti-inflammatory activity in carrageenan-induced rat paw oedema assay, and their effects are found to be comparable that of standard drug Indomethacin. Molecular docking studies were further employed to investigate the binding interactions to COX-2 active site residues and to study the stability of docked conformation in detail. The experimentally determined COX-2 inhibitory activity was found to be well correlating with binding modes predicted for compounds by GLIDE dock scoring function. The 2,3-diaryl-2,3-dihydro-1H-quinazolin-4-one pharmacophore reported herein represents a new lead for further development of novel non-steroidal anti-inflammatory...

Nature is always being a consistent and constant source of medicinal substances for prevention and cure of various ailments, including the helminth infections, which is one of the health problems that affect human and livestock in the world. Because of limited availability/ accessibility of anthelmintic compounds in modern medicine, and reawakened worldwide interest in plants based medicine, the present study was undertaken to evaluate the anthelmintic activity of the stem bark of Plumeria rubra (Syn. Plumeria acutifolia) along with the qualitative and quantitative estimation of phytochemicals present in the stem bark of P. rubra, family Apocynaceae – one of the ten largest angiosperm families and comprises of several prominent medicinal plants. Out of five extracts prepared, the methanolic extract showed better yield and hence used for the present study. Preliminary phytochemical investigation reflected the presence of many phytoconstituents, mainly – alkaloids, glycosides, tannin, terpenes, flavonoid, phenol, saponin. The in-vitro anthelmintic study of stem bark extract of P. rubra with reference to standard Piperazine citrate showed prominent results in concentration...
