the solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. fused dispersions (fds) of simvastatin (sim) using peo-ppo block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. the accumulative solub...

Equilibrium constants of Cadmium Oxide (CdO) nanoparticles complexes in human cancer cells with DNA/RNA ligands have been studied with biospectroscopic methods such as 1HNMR, 13CNMR, 31PNMR, Attenuated Total Reflectance Fourier Transform Infrared (ATR–FTIR) and FT–Raman spectroscopies in cosolvent systems at 10, 20, 30°C ± 0.5 and 1 mol.dm–3 ionic strength, was maintained using Sodium Chloride ...

A series of Pyrano[2,3-d]Pyrimidine derivatives were synthesis using Knoevenagel and Michael addition reaction. Investigation of antimicrobial properties were done against gram positive bacteria Staphylococcus(NCTC-7447),Bacillus cereus(ATCC-14579) and gram negative bacteria Serratia maresens(IMRU-70), Proteus merabitis (NTCC-289) using Ampicillin as standard drugs. These synthesized compounds ...

Synthesis of Some Benzimidazole derivatives 4'-(5, 6-substitued-2-trifluoromethylbenzoimidazol-1-ylmethyl)-biphenyl-2-carboxylic acid were synthesized by condensation of various steps with different o-Phenylenediamine was condensed with in propylene glycol was added trifluoroacetic acid in the presence of BF3•OEt2 as catalysis. Elemental analysis, IR, 1HNMR and mass spectral data confirmed the ...

Abstract Derivatives of formyl pyrazole were synthesized by the reaction acetophenone, 4-methyl 3-acetyl furan, thiophen and phenyl hydrazine derivatives. The product was treated with Vilsmeier reagent producing different derivatives which characterized FT-IR, 1HNMR, Elemental analysis Mass spectroscopy. reacted chitosan to produce chitosan/ Schiff base. These bases FT-IR TGA.The antimicrobial ...

Cheilanthes grisea Blanford, a rare fern of Kumaun hills, is a member of psinopteridaceae family of leptosporangiate group of ferns. Aq. methanolic extract (50%) of this fern was screened for antifungal activity by thin layer autobiochromatographic methods. Chemical investigation of the fern fronds of C. grisea Blanford revealed the presence of a flavonol glycoside, quercetin-3-O-β-glycosyl (1→...

Flavones and chromanones are known to be biologically important compounds over 4000 chemically unique flavanoids have been identified in plant sources. These low-molecular-weight substances, found in all vascular plants, with an assortment of basic structure of phenyl benzopyrones (phenyl chromones). In the present work 2-hydroxy pyrimidine and 2-mercapto pyrimidine were prepared from phenol i....

Conventional cancer treatments normally involve chemotherapy or a combination of radio- and chemotherapy. However, the adverse effects synthetic medicines encouraged exploration novel therapeutic medications bio-friendly nature. In an effort to explore anticancer compounds from natural resources, crude extract Peganum harmala (seeds) was fractionated on basis polarity, fractions were further te...
