Nigella sativa (NS) is a commonly used herb in Asian and African countries. Extensive experimental studies have been done to shed light on its hepatoprotective, immunumodulator, antioxidant, antimicrobial and several other useful pharmacological properties. However, there is dearth of evidence to evaluate the effect of Nigella sativa extract in neuropathic pain. In this study we have used neuropathic pain model of Wistar rats using intraperitoneal cisplatin injection twice weekly for 4.5 weeks. Animals were divided into six groups of six rats each. Ethanolic extract of Nigella sativa, pregabalin, tramadol or combination of pregabalin and tramadol were given orally in Wistar rats in which neuropathy had been induced by cisplatin i.p. injections for 4.5 weeks. Single dose of drugs were given and pain assessment was done by soft touch, crude touch, Eddy’s hotplate and tail flick analgesiometer at 0, 30, 60, 90, 120 and 240 minutes. Nigella sativa showed significant analgesic effect on cisplatin induced neuropathic pain in all the experiments however pregabalin and tramadol showed better...

Pyrazoline, among the various 5-membered heterocyclic compound derivatives has drawn attention towards it because of its various pharmacologically activities associated with it. Pyrazolines are a five membered heterocyclic having two adjacent nitrogen atoms within the ring with only one endocyclic double bond and is basic in nature. A lot of research work has been done on synthesis and biological activities of various pyrazoline derivatives over the years. Pyrazolines derivatives display tremendous biological activities such as antimicrobial, anti-inflammatory, analgesic, antipyretic, antidepressant, antitubercular, antiamoebic, anthelmintic, anticonvulsant, antihypertensive, antidiabetic, antitumor, anti-HIV, local anaesthetic, antioxidant, insecticidal, tranquilizing and receptor selective biological activity. The history of pyrazoline shows that it attracted many chemists to explore pyrazoline as a biologically active molecule. The study of biological evaluation of pyrazoline derivatives has been an interesting field of pharmaceutical chemistry. This review article focuses on the pharmacological profile of pyrazoline with various activities and examples in form of...

A series of novel 2- substituted benzothiazole dithiomidocarbonate derivatives were synthesized by the reaction of 2-amino benzothiazole with various halides. The test compounds were screened for their antimicrobial activity (antibacterial and antifungal) by disc diffusion method and the results of the microbial activity indicates that the test compounds exhibited varying degree of antimicrobial activity. Among the substituents benzyl moiety exhibited the most potent activity and the compound Dibenzyl (1,3 benzothiazo-2yl) Dithioimidocarbonate(4T1) emerged as the most active antimicrobial agent and it is equipotent when compared to the reference standard Ciprofloxacin. Among the substituents propyl moiety exhibited the most potent activity and the compound Dipropyl (1,3 benzothiazo-2yl) Dithioimidocarbonate (4T3) emerged as the most active antifungal agent and it is equipotent when compared to the reference standard ...

The present study depicts formulation and characterization of boric acid gel formulations. The formulated gels intervenes the advantages of gels along with higher and effective antimicrobial activity when compared to the formulations available in the market. The preparations were evaluated for different parameters as basic physico-chemical properties like physical appearance, texture, pH measurement, spreadability, viscosity and spectral analysis (UV-Visible and IR Spectroscopy) for its standardization. The sharp peak at 230nm was obtained in UV-Vis spectra. I.R spectra revealed that the boric acid binds extensively to the polymers. Antimicrobial activity of formulation was studied using Muller Hinton agar medium against E.coli MTCC 614 and S.aureus MTCC...

The aim of the present study was to investigate the antifungal potential of trypsin inhibitors (AMTI-I and AMTI-II) isolated from the seeds of Abelmoschus moschatus on selected pathogenic fungal strains. The purified inhibitors have been found to be homogenous by the criteria of native PAGE and gel filtration with apparent molecular weights of 22.4kDa and 21.2 kDa as judged by SDS-PAGE. While both the inhibitors were strongly active against bovine trypsin, they showed moderate effect on porcine elastase. AMTI-I and AMTI-II significantly affected the growth of Candida albicans, Candida tropicalis, Asperigillus flavus, Saccharomyces cerevisiae, Candida glabrata and Asperigillus niger with notable zones of inhibition. The inhibitors, however, did not show any inhibitory effect on the growth of other fungal strains- Fusarium oxysporum, Alternaria alternate, Mucor indicus and Penicillium chrysogenum. The fungicides, Flucanazole and Ketoconazole were used as positive controls in this study. Results obtained suggest that AMTI-I and AMTI-II may be regarded as excellent candidates for the development of novel antimicrobial agents against human pathogenic...
