TO INVESTIGATE THE EFFECT OF SPAN 60 AND SPAN 80 POLYMER ON RELEASE RATE OF SIMVASTATIN NOISOME IN COMPARISON WITH PURE SIMVASTATIN
The main objective of the present study was to develop and evaluate the simvastatin noisome using different grades of nonionic surfactants. It was hypothesized that niosomes would increase in vitro release of simvastatin in comparison to the API Mumbai. Niosome were prepared by thin-film hydration method and evaluated for particle size, entrapment efficiency, PDI, and in vitro release. The differe...

DESIGN, SYNTHESIS AND ANTIMICROBIAL EVALUATION OF NOVEL 1-(2-(4-FLUORO BENZYLTHIO)PYRIMIDIN-4-YL-AMINO)-4-(SUBSTITUTED PHENYL)AZETIDIN-2-ONES
A series of novel 1-(2-(4-fluorobenzylthio)pyrimidin-4-yl-amino)-4-(substituted phenyl)azetidin-2-one analogues (3a-e) were synthesized starting from 2-thiouracil. Reaction of 2-thiouracil with 4-fluorobenzylchloride gave 2-(4-fluorobenzylthio) pyrimidin-4(3H)-one which on chlorination with POCl3 yielded 2-(4-fluorobenzylthio)-4-chloropyrimidine. Further reaction of compound 2-(4-fluorobenzylthio)...

THERMAL AND STRUCTURAL PROPERTIES OF IRRADIATED SILVER/POLY (VINYL ALCOHOL) (Ag/PVA) NANOCOMPOSITES USING ARGON ION BEAM
Structural and thermal properties of silver/poly(vinyl alcohol) (Ag/PVA) nanocomposites has been investigated as a function of Argon ion beam fluence. The XRD patterns (X-ray diffraction) showed the formation of the Ag/PVA in polymer structure and phase analysis with different sizes as a function of either ion beam fluence or Ag+ ion molar concentrations. The kinetic parameters for the thermal s...
