Cancer is the major cause of mortality in most of the developing countries. Recent times have seen an exceptional advancement in cancer biology Research. Researchers undertook the development of enormous chemotherapeutic agents. Pim family of serine/threonine kinases regulated by calcium/calmodulin have been identified as unique molecular targets in oncogenesis. It constitutes three members: Pim-1, Pim-2, and Pim-3 discovered by cloning the proviral integration site in Moloney murine leukemia virus (M-MuLV). Pim-1 was found to bear two isoforms Pim-1S and Pim-1L. It plays a dominant role in various processes of cell regulation like replicative senescence, drug resistance, apoptosis, epidynamics regulator, diagnostic tool, prostate cancer biomarker, and an immunotherapy agent. An insight into the structure of Pim kinases by crystal studies laid down a molecular basis for the development of selective and synergistic anti-cancer therapies. These proto-oncogenes are overexpressed in B lymphoid, myeloid cell lines, hematopoietic malignancies, and prostate cancer. This review emphasizes the importance and role of Pim-1 kinase in various molecular signaling pathways involved in tumorigenesis and the potential...

The aim of the present study was to develop a controlled release formulation of Lornoxicam to maintain constant therapeutic levels of the drug for over 12 h. Guar gum, xantham gum, and carbopol 934 were employed as polymers. All the formulations were passed various physicochemical evaluation parameters, and they were found to be within limits. From the dissolution studies, it was evident that the formulation (F2) showed better and desired drug release patterns, i.e., 99.65% in 12 h. It contains the guar gum polymer. It followed the Higuchi order release kinetics...

The development of analytical methods is in need for the estimation of drugs in pure and different pharmaceutical formulations. A simple, sensitive, rapid, accurate, precise and economic spectrophotometric and spectro-fluorimetric method was developed and validated for Nadolol in pure and pharmaceutical formulations. The proposed method was validated according to the International Conference on Harmonization (ICH) guidelines. The wave length (λmax) used for the estimation of Nadolol is 267 nm by spectrophotometry, excitation (λEx)-267 nm and emission (λEm)-300 nm by spectrofluorimetry. The linearity of the calibration curve was validated by the high values of the correlation coefficient of regression. The percentage of drugs recovered 100.37 ± 0.94% and 99.9 ± 0.59% for spectrophotometric and spectrofluorimetric methods respectively. LOD and LOQ values for Nadolol were found to be 3.531 µg/ml and 10.70 µg/ml by spectrophotometry and 0.45 µg/ml and 1.37 µg/ml by spectrofluorimetry. The developed methods are simple and suitable for the determination of Nadolol in pure and pharmaceutical...

Ageratina adenophora, often known as Crofton Weed, is one of the common invasive weeds which first originated from Mexico and Central America and gradually invaded numerous parts of the world. Because of its ability to alter the soil microbial communities and its allelopathic competition with other plant species, this plant colonizes forest margins, stream banks and disturbed areas in large dense clumps and is found to possess potent toxicological effects on livestock; the lethal chronic pulmonary disease has been reported in horses while liver complications have been reported in mice. Despite this, the plant has been studied more extensively for its therapeutic uses as phytochemicals viz. steroids, tannins, triterpenes, coumarins and saponins (7-hydroxy-dehydrotremetone, 7, 10,1 1-trihydroxy-dehydrotremetone, 10-oxo-7-hydroxynordehydro-tremetone,Eupatorone, 2-deoxo-2-(acetyloxy)-9-oxoagera-phorone(DAOA), 9-oxoagerophorone(OA), etc.) which have been reported are found to possess antimicrobial activity, antipyretic activity, wound healing, antioxidant activity, analgesic activity, anti-tumor activity, insecticidal activity, antiviral activity, anti-inflammatory activity, larvicidal activity. This present review is an effort to give a detailed survey of the literature on invasive nature, pharmacological study, phytochemical review,...

Psidium guajava Linn. the most popular and widely cultivated fruiting plant all over Bangladesh. The present study was aimed to investigate the antioxidant, analgesic and antimicrobial activities of n-hexane (HPG), chloroform (CLPG) and ethyl acetate fractions (ET APG) obtained from methanol extract of Psidium guajava (MPG) leaves. The in-vitro antioxidant activity of fractions HPG, CLPG and ET APG were determined using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and ascorbic acid was used as standard. The IC50 value of HPG, CLPG and ET APG were 29.96 µg/ml, 26.84 µg/ml and 24.29 µg/ml respectively whereas the IC50 value of ascorbic acid was 6.23 µg/ml. Analgesic activity of HPG, CLPG and ET APG extracts (400 mg/kg) were evaluated using acetic acid-induced writhing model of pain in mice and demonstrated significant reduction of pain in mice with the effect of 56.10%, 60.51% and 70.12% respectively (p<0.05) and were comparable to that of standard, diclofenac sodium (77.22%). Preliminary phytochemical screening of different fractions showed the presence of bioactive constituents like alkaloids, saponin, flavonoids, tannins and triterpenoids. Further,...
