Antagonists of signaling receptors are often effective non-toxic therapeutic agents. Over the years, there have been evidences describing the role of serotonin or 5-hydroxytryptamine (5-HT) in development of cancer. Although there are reports on the antiproliferative effects of some serotonin receptor antagonists, there are very few investigations related to understanding their structure-activity relationships. In this study, we report the screening of a library of 4-phenyl quinoline derivatives for their antiproliferative activities. Preliminary docking studies indicated that these ligands had the ability to bind to two of the serotonin receptors, 5-HT1B and 5-HT2B. The results of the in silico experiments were validated by performing in vitro studies on MCF-7 breast cancer cell line. The ethylpiperazine derivatives showed maximum toxicity against this cancer cell line. The compounds inhibited Calcium ion efflux (induced by serotonin) and ERK activation. One of the most active 4-phenyl quinoline derivatives (H3a) also induced apoptosis, thereby, suggesting the use of this scaffold as a potential anticancer drug. © 2017 Elsevier Masson SAS

Tuberculosis (TB) has been declared as a health emergency due to emergence of resistant strains of M. tuberculosis, multidrug resistant (MDR), extensively drug resistant (XDR) TB strains and totally drug resistant tuberculosis (TDR-TB) reported recently in some parts of the world. Therefore, the current situation necessitates developing new antitubercular agents acting on novel targets for effectively controlling TB. Thymidine Monophosphate Kinase (TMPKmt) enzyme is one such target, which is being explored. This review focuses on Structure Activity Relationship studies (SARs) and computational studies of various nucleotide and nucleoside derivatives of pyrimidine analogs reported as TMPKmt inhibitors. © 2016 Bentham Science Publishers.

The present study aims to assess and compare the biochemical oxidative stress markers in male smokers and non-smokers with chronic periodontitis. One hundred thirty-four male chronic periodontitis patients and 64 apparently healthy male volunteers were recruited for the study. The periodontal status was evaluated by measuring gingival index, plaque index, papillary bleeding index and clinical attachment loss using UNC-15 probe. The biochemical markers estimated were total antioxidant capacity, RBC-superoxide dismutase, glutathione peroxidase, vitamin C, malondialdehyde and C-reactive protein. The obtained results indicate higher oxidative stress in chronic periodontitis. Smokers with chronic periodontitis show significantly higher periodontal clinical parameters and relatively higher systemic oxidative stress. Vitamin C estimation may be an important biochemical parameter in conjunction with clinical parameters for diagnosis of chronic periodontitis in smokers. © 2013 Association of Clinical Biochemists of India.

Adequate intake of calcium is important for skeletal growth. Low calcium intake during childhood and adolescence may lead to decreased bone mass accrual thereby increasing the risk of osteoporotic fractures. Our aim was to study dietary calcium intake and sources of calcium in adolescents from lower and upper economic strata in Pune, India. We hypothesized that children from lower economic strata would have lower intakes of calcium, which would predominantly be derived from non-dairy sources. Two hundred male and female adolescents, from lower and upper economic stratum were studied. Semiquantitative food frequency questionnaire was used to evaluate intakes of calcium, phosphorus, oxalic acid, phytin, energy and protein. The median calcium intake was significantly different in all four groups, with maximum intake in the upper economic strata boys (893 mg, 689-1295) and lowest intake in lower economic strata girls (506 mg, 380-674). The median calcium intake in lower economic strata boys was 767 mg (585-1043) and that in upper economic strata girls was 764 mg (541-959). The main source of calcium was dairy products in upper economic strata adolescents while it was dark green leafy vegetables in lower economic strata adolescents. The median calcium intake was much lower in lower economic strata than in the upper economic strata both in boys and girls. Girls from both groups had less access to dairy products as compared to boys. Measures need to be taken to rectify low calcium intake in lower economic strata adolescents and to address gender inequality in distribution of dairy products in India.

Vitamin D deficiency is common among children and adolescents in India, in spite of abundant sunshine. We conducted a pilot; double blind randomised controlled trial to investigate the effect of vitamin D supplementation on bone mineral content in underprivileged adolescent girls, in Pune, India. Fifty post-menarcheal girls aged 14 to 15 years were randomised to receive 300,000 IU (7.5 mg) of ergocalciferol or placebo orally, 4 times/year. All participants received 250 mg elemental calcium (calcium carbonate) daily. Outcome measures included change in serum 25-hydroxyvitamin D, size adjusted bone area and bone mineral content at total body and lumbar spine. Post supplementation, the median serum concentration of 25-hydroxyvitamin D was 75.2 (64.2-85.5) nmol/L in the intervention group and 28.1 (16.7-34.0) nmol/L in the placebo group. Increment in bone outcome measures was not different in the two groups. However, there was a positive effect of intervention in the size adjusted total body bone area (p<0.05), total body bone mineral content (p<0.05) and lumbar spine bone mineral content (p<0.05), and positive trend in lumbar spine bone area (p=0.07) in girls who were within 2 years of menarche. We conclude that vitamin D supplementation did not have a beneficial effect on skeletal mineralization in girls who were more than 2 years post menarcheal. However, there was a significant positive effect of the intervention on size adjusted total body and lumbar spine bone mineral content and a positive trend in lumbar spine bone area, in girls who were ≤ 2 years of menarche.

Stabilization of mutant p53 (mutp53) in tumours greatly contributes to malignant progression. However, little is known about the underlying mechanisms and therapeutic approaches to destabilize mutp53. Here, through high-throughput screening we identify statins, cholesterol-lowering drugs, as degradation inducers for conformational or misfolded p53 mutants with minimal effects on wild-type p53 (wtp53) and DNA contact mutants. Statins preferentially suppress mutp53-expressing cancer cell growth. Specific reduction of mevalonate-5-phosphate by statins or mevalonate kinase knockdown induces CHIP ubiquitin ligase-mediated nuclear export, ubiquitylation, and degradation of mutp53 by impairing interaction of mutp53 with DNAJA1, a Hsp40 family member. Knockdown of DNAJA1 also induces CHIP-mediated mutp53 degradation, while its overexpression antagonizes statin-induced mutp53 degradation. Our study reveals that DNAJA1 controls the fate of misfolded mutp53, provides insights into potential strategies to deplete mutp53 through the mevalonate pathway-DNAJA1 axis, and highlights the significance of p53 status in impacting statins' efficacy on cancer therapy. © 2016 Macmillan Publishers Limited. part of Springer Nature All rights reserved.

The development of prostate cancer and its progression to castrate-resistant prostate cancer (CRPC) after antiandrogen ablation therapy are driven by persistent biological activity of androgen receptor (AR) signaling. Moreover, studies have shown that more than 50% of human prostate cancers overexpress ERG (v-ets avian erythroblastosis virus E26 oncogene related gene) due to AR-regulated TMPRSS2-ERG fusion gene. However, the reported roles of TMPRSS2-ERG fusion in cancer progression are not clear. In this study, we investigated the signal transduction in the AR/TMPRSS2-ERG/Wnt signaling network for studying the aggressive behavior of prostate cancer cells and further assessed the effects of BR-DIM and CDF [natural agents-derived synthetic formulation and analogue of 3,3′-diindolylmethane (DIM) and curcumin, respectively, with improved bioavailability] on the regulation of AR/TMPRSS2-ERG/Wnt signaling. We found that activation of AR resulted in the induction of ERG expression through TMPRSS2-ERG fusion. Moreover, we found that ERG overexpression and nuclear translocation activated the activity of Wnt signaling. Furthermore, forced overexpression of ERG promoted invasive capacity of prostate cancer cells. More important, we found that BR-DIM and CDF inhibited the signal transduction in the AR/TMPRSS2- ERG/Wnt signaling network, leading to the inactivation of Wnt signaling consistent with inhibition of prostate cancer cell invasion. In addition, BR-DIM and CDF inhibited proliferation of prostate cancer cells and induced apoptotic cell death. On the basis of our findings, we conclude that because BR-DIM and CDF downregulate multiple signaling pathways including AR/TMPRSS2-ERG/Wnt signaling, these agents could be useful for designing novel strategies for the prevention and/or treatment of prostate cancer. ©2011 AACR.

The biosorption of Cr(VI) onto wood apple shell, batch adsorption experiments have been studied. Equilibrium adsorption isotherms, adsorption kinetics and thermodynamic parameters have been analyzed. The Langmuir monolayer adsorption capacity of wood apple shell for Cr(VI) was determined and was found to be 28.81, 29.58 and 31.45mgg-1 at 299, 309 and 319 K, respectively. The analyzed kinetic data were following the pseudo-second order model. The thermodynamic parameters, such as Gibbs free energy change (ΔG°), enthalpy change (ΔH°) and entropy change (ΔS°) were calculated and interpreted. The negative value of Gibbs free energy change and positive value of enthalpy change indicate that biosorption is spontaneous and endothermic in nature, respectively. The standard zero free energy temperature (T°) of biosorption process is 274.6 K. Infrared spectroscopy study revealed the mechanism of Cr(VI) biosorption on powdered wood apple shell. Wood apple shell powder was shown to be a promising biosorbent for Cr(VI) removal from aqueous solutions. © 2012 Desalination Publications. All rights reserved.

India has been blessed with rich source of medicinal plants that have been used since ages to cure diseases. Unani system of medicine is an ancient system of medicine that relies on natural drugs. Due to the growing problem of multi-drug resistance, skin infections have become very common. The skin pathogens like Staphylococcus aureus, Candida albicans, Pseudomonas aeruginosa and Escherichia coli are responsible for severe skin infections. Unani plants, source of wide range of secondary metabolites possessing antimicrobial properties can be harnessed to treat these pathogens. In this study, twelve plants were assessed for their antimicrobial properties by subjecting them to extraction using various solvents. It was found that methanol extracts of plants exhibited maximum antimicrobial activity against Staphylococcus aureus and Candida albicans. Effect of metals like silver and iron were also studies on methanol extracts of Psoralea corylifolia and Embelia ribes. It was found that combination of silver nitrate with these extracts were effective against Gram negative pathogens.
