Evaluation of multicomponent synergy is a critical point in current drug combination studies. However, it is still an ongoing challenge to prioritize the synergistic combination from various pharmacological agents in a high throughput manner. Here we proposed a network target-based approach termed NIMS (Network target-based Identification of Multicomponent Synergy), and showed that NIMS can not...
An eco-friendly synthesis of highly functionalized epoxides and their incorporation into an organocatalytic multicomponent approach are reported. For this, a modified class of diarylprolinol silyl ethers was designed to enable high catalytic activity in an environmentally benign solvent system. The one-pot procedure showed great efficiency in promoting stereoselective multicomponent transformat...
A methodological study devoted to the Mannich-like multicomponent synthesis of the antiplatelet agent (±)‑clopidogrel (7) and the ethyl ester analogue 6 is described. The process involves the formation of 2-chlorophenyl zinc bromide (2) and its subsequent reaction with an alkyl glyoxylate and 4,5,6,7-tetrahydrothieno[3,2-c]pyridine (3). We demonstrate that the organozinc reagent 2 also constitu...
Based on a well-known Lie algebra, the multicomponent Guo hierarchy with self-consistent sources is proposed. With the help of a set of non-semisimple Lie algebra, the nonlinear biintegrable couplings of the multicomponent Guo hierarchy with self-consistent sources are obtained. It enriches the content of the integrable couplings of hierarchies with self-consistent sources. Finally, the Hamilto...
the aim of the present work is to prepare an adsorption package to simulate adsorption / desorption operation for both single and multi-component systems in an isothermal condition by different mechanisms such as; local adsorption theory and mass transfer resistance (rigorous and approximated methods). different mass transfer resistance mechanisms of pore, solid and bidispersed diffusion, toget...
aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. this contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. the method is ba...
a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...
