بتا-سیکلودکسترین ، قادر به تشکیل کمپلکس محاطی inclusion complex)) با شمار زیادی از مولکولها از جمله داروهای کم محلول و ناپایدار و ... است که در نتیجه تشکیل این کمپلکس ، حلالیت و پایداری این داروها افزایش می یابد.
چکیده در این پایان نامه، در ابتدا از واکنش بین پالادیم استات و آلیزارین زرد gg کمپلکس دو هسته ای ارتوپالادیت [pd{? 2(c,n) -{5-(3-nitrophenylazo) salicylic acid}}(µ-oac)]2 (1) ستنز شد. از واکنش این کمپلکس دو هسته ای ارتوپالادیت (1) با لیگاند های تک دندانه تری فنیل فسفین (pph3)، 6،4،2-تری متیل-پیریدین(me3py) کمپلکس های تک هسته ای (2)، (3) سنتز شدند. همچنین از واکنش بین پالادیم استات و آلیزارین ز...
a powerful and convenient reaction procedure for the c-n coupling reaction (the buchwald-hartwig reaction), yielding products of n-arylanilines and n-arylamines in both conventional heating and microwave irradiation has been reported. the protocol utilizes a stable and new supper ferromagnetic nanoparticle chelating n-heterocyclic dicarbene palladium(ii) complex (pd-nhc) as catalyst which helps...

vinblastine is an important anticancer agent known to diminish microtubule assembly. ab initio calculations are applied to examine the structural properties and different energies of vinblastine-tubulin complex in different dielectric constants and temperatures. the aims of this work are discovery the best optimized structure and thermodynamic properties of vinblastine-tubulin complex and compa...
In 1972 May showed that for a large linear system with random coupling the system size and the average coupling strength must together satisfy a simple inequality to ensure the stability of the equilibrium point. Here we extend the analysis to delay coupled systems. Our calculations establish that the same inequality obtained by May constrains the stability for systems randomly coupled through ...
Abstract. One describes, using a detailed analysis of Atiyah–Hirzebruch spectral sequence, the tuples of cohomology classes on a compact, complex manifold, corresponding to the Chern classes of a complex vector bundle of stable rank. This classification becomes more effective on generalized flag manifolds, where the Lie algebra formalism and concrete integrability conditions describe in constru...
