Despite the noteworthy advances in the use of chemotherapy for malaria, it continues to constantly affect large number of individuals. New molecules capable of blocking life-cycle of the parasite, preferably through targeting novel pathways and various modes of action, are increasingly becoming area of interest. Phenotypic screening of large chemical libraries is certainly one of the important criteria for the discovery of new and effective drugs. In recent years, diverse research groups including pharmaceutical industries have performed this large-scale phenotypic screening to identify the potential drug molecules. Most of the antimalarial drugs target blood-stage malarial infection and remain either less potent or ineffective against other life stages i.e. liver-stage, and the gametocyte stages of the parasite. Although, liver stage is considered as a crucial drug target, limited clinical options have significantly hampered the discovery of effective treatments. This short review presents the collection of selective molecules targeting specifically liver stage malaria parasites.

2-Methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) were synthesized by one pot multicomponent aza Diels-alder reaction between N-arylimines with two molecules of N-vinyl-2-pyrrolidinone in presence of Sm(III)nitrate as catalyst in acetonitrile solvent at room temperature stirring. The photocleavage studies with 2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) revealed that almost all derivatives exhibited effective photocleavage of pUC−19 DNA at 365 nm, The The anticancer activities of newly synthesized compounds (3a−g) were more potent than doxorubicin on MCF−7 cells. The docking of PBR receptor (1EQ1) protein with newly synthesized THQ’s (3a-g) exhibited well established bonds with one or more amino acids in the receptor active pocket.

The first issue of Pharmacy Journal in India – The Indian Journal of Pharmacy was published in Dec 1894, however it was defunct after 3 years. The Modern Pharmaceutical Journalism in India was Pioneered by Mr. Premnath Bazaz, who started the Eastern Pharmacist in 1958 and equal contribution was by Dr. A.K. Patni, who edited Indian Drug since its inception published by IDMA. Today there are nearly 175 Pharmacy Journal published in mostly English (and also in Marathi, Hindi & Bengali) by 5 different categories of publishers in India. The PCI has set out official Journals – seven – for D. Pharm Course and 20 for B. Pharm Degree Course, and minimum 2 international Journals for each discipline of specialization at M. Pharm, Ph.D and Pharm. D Courses structure in India. This article brings out short History and progress of Indian Pharmacy Periodical as on today.
In this paper, we report the fabrication of carbon nanofibers (CNFs) by electrospinning of polyacrylonitrile (PAN) solution in N,N-dimethylformamide (DMF)with different concentrations followed by stabilization and carbonization in a tubular quartz furnace. To improve the electrochemical performance, graphene nanosheets have been used to prepare porous graphene/carbon nanofibers (G-CNFs). The morphology of the porous G-CNFs were characterized by means of scanning electron microscopy (SEM). Diameter of CNFs and G-CNFs were found to be in the range of 400 – 500 nm reveals the fibers in nanoscale with high porosity. The electrochemical performance of as-synthesized CNFs and G-CNFs was studied by cyclic voltammetry (CV), galvanostatic charge discharge (GCD) and electrochemical impedance spectroscopy. The CV curve of the pure CNFs show distorted rectangular shape whereas CV curve of G-CNFs exhibit a nearly rectangle-shaped profile which is the characteristic of an ideal electric double-layer capacitor. The improved electrochemical performance of G-CNFs is due to the improved internal electrical conductivity of G-CNFs via graphene nanosheets interlaying.

Nanostructured materials has appealed considerable attention due to their characteristic properties and applications in different fields. Metal nanoparticles supported on modified montmorillonite composites have led to the generation of new and novel heterogeneous ‘Nanocatalysts’, which are much more efficient than other catalysts and thus pave the way for developing sustainable environmentally benign catalysis and chemical procedures. Such nanocatalysts are progressing towards their use in chemical industries. This review presents the recent trend of advances in the synthesis and catalytic reactions of supported metal nanoparticles on acid activated montmorillonite. Metals nanoparticles-montmorillonite composites show efficient catalytic activities with high conversions and selectivity for hydrogenation, transfer hydrogenation, oxidations and coupling reactions. Raw montmorillonite possess no catalytic activity, however acid activated montmorillonite exhibits excellent acid catalytic activities.

In present work, the role of various formulation excipients for
dissolution enhancement of a BCS Class II drug, meloxicam was studied by
formulating multicomponent aqueous coground mixtures using lactose,
microcrystalline cellulose and three solubilizers; polyethylene glycol
400, propylene glycol and polyvinyl pyrrolidone. A 33 full factorial design was employed using solubilizers’ concentrations as independent variables whereas angle of repose and in vitro
drug dissolution as dependent variables in order to optimize the
amounts of solubilizers. The results revealed more than fivefold
increase in drug dissolution in some experimental batches compared to
that of pure drug powder. Full and reduced models were evolved for the
dependent variables and the reduced models were further validated using
extra design check points. The studies suggested that the incorporation
of optimized amounts of solubilizers could be successfully employed for
achieving desired flow properties and enhanced drug dissolution of
poorly water soluble meloxicam. The method emerged as a simple,
cost-effective, and organic solvent-free green approach toward
formulation development of meloxicam and may also be applied to other
limited water-soluble drugs.

Carissa carandas (CC) has been used in folklore medicine for treatment of diabetes. In the present study, hexane, chloroform, ethyl acetate, methanol and aqueous extracts of CC fruit were examined for hypoglycemic activity in healthy Wistar rats. Aqueous Extract of CC (AECC) was most active and showed fall of 67.08% in fasting blood glucose from 0 to 1h in glucose tolerance test (GTT). The ED50 of AECC was 300mg/kgbw in streptozotocin induced diabetic rats. Treatment of diabetic rats with ED50 of AECC for 28 days significantly reduced post prandial glucose (PPG) by 33.65% (p<0.01), glycosylated hemoglobin (HbA1c) by 45.79% (p<0.01) and increased insulin level by 69.7% (p<0.05). The results indicated that increase in insulin secretion may be partly responsible for antidiabetic effect of AECC. To assess the mechanism of secretagogues activity, AECC was incubated with isolated pancreatic islets of healthy Wistar rats at basal (3.3mM) and high (16.7mM) level of glucose in presence or absence of Diazoxide (K-ATP channel opener), Nimodipine (Ca2+ Channel blocker) and Calphostin-C (PKC inhibitor). AECC induced insulin secretion at 16.7mM of glucose was significantly (p<0.01) reduced by Diazoxide and Nimodipine but non significantly (p>0.05) by Calphostin-C. The study indicated that the phytochemicals present in AECC may be inducing insulin secretion by closing K-ATP channels in β-cells of pancreatic islets.
