Multicomponent reactions: A mighty journey partner for infectious tropical disease drug discovery

Infectious tropical diseases such as malaria, tuberculosis, and the so-called neglected tropical diseases are causing tremendous suffering to millions of people and huge impact on national economies, seriously worsening life conditions in the poorest parts of the world, where these diseases are endemic. Despite the existence of drugs for most of these diseases, they are far from adequate. Lack of efficacy, toxicity, and emergence of pathogen resistance are among the most important flaws of currently available drugs. Thus, apart from improving prevention and vector control measures, there is an urgent need for developing new efficacious, safe, and inexpensive drugs that desirably feature novel chemotypes. Multicomponent reactions (MCRs), where three or more reactants are combined in a one-pot reaction, constitute a very powerful tool for such endeavors, inasmuch as they enable a very rapid access to structurally diverse, usually complex scaffolds, shortening the synthesis of the novel drugs and, hence, lowering production costs, and affording original chemotypes. In this chapter, we provide an overview of the application of different types of MCRs to drug discovery against infectious tropical diseases, with particular emphasis on how structural complexity and molecular diversity can be readily introduced through their use.

Design, synthesis and biological evaluation of new substituted 5-benzylideno-2-adamantylthiazol[3,2-b][1,2,4]triazol-6(5H)ones. Pharmacophore models for antifungal activity

As a part of our ongoing studies in developing new derivatives as antimicrobial agents we describe the synthesis of novel substituted 5-benzylideno-2-adamantylthiazol[3,2-b][1,2,4]triazol-6(5H)ones.The twenty-five newly synthesized compounds were tested for their antimicrobial and antifungal activity. All compounds have shown antibacterial properties with compounds 1?9 showing the lowest activity, followed by compounds 10?14 while compounds 15?25 the highest antibacterial activity. Specific compounds appeared to be more active than ampicillin in most studied strains and in some cases more active than streptomycin. Antifungal activity in most cases also was better than that of reference drugs ketoconazole and bifonazole. Elucidating the relation of molecular properties to antimicrobial activity as well as generation of pharmacophore model for antifungal activity of two fungal species Aspergillus fumigatus and Candida albicans were performed.

Preparation and characterization of new In(III), Re(III), and Re(V) complexes with thenoyltrifluoroacetone and some bidentate heterocyclic ligands

New In(III), Re(III) and Re(V) complexes with the thenoyltrifluoroacetone ligand (HTTA) of the general formulae [In -(TTA)(H2O)4]SO4, [Re(TTA)n(H2O)x]Cl3-n and [ReO(TTAn-(H2O)x]Cl3-n (where n and x refer to the number of [TTA]- moieties and H2O molecules, respectively) have been prepared and characterized by spectroscopy, thermogravimetry, elemental analyses and X-ray diffraction. The charge densities on the ligand atoms were calculated via CNDO-SCF calculations. The newly prepared complexes [In(TTA)(H2O)4]SO2 and [ReO(TTA)(H2O)2]CL2 were employed as precursors for the synthesis of the mixed-ligand complexes [In(TTA)(HOCTA)2], [In(TTA)(TZT)2] and [ReO(TTA)(HOTCA)]Cl using R(-)-2-oxothiazolidine 4-carboxylicacid (H2OTCA) and 1H-1,2,4-triazole-3-thiol (H2TZT) as ligands. The synthesized mixed-ligand complexes were characterized by the conventional physical and chemical methods of analysis applied earlier for the characterization of the precursors. The investigated complexes are soluble in water, ethanol and acetonitrile, insoluble in non-polar solvents and could be of potential use for clinical studies. The antibacterial activity of the investigated complexes has been tested and evaluated.

Synthesis and collateral dilator activity of nitroxyalkylamides having direct or latent sulfhydryl moieties

To develop an orally active, long-acting nitrate that does not induce tolerance, nitroxyalkyl compounds were prepared and their activities evaluated by the use of carotid collaterals in anesthetized dogs. A compound having a favorable pharmacological profile, that is, long-lasting collateral vasodilatation and little hypotension, and lack of nitrate tolerance, was chosen for further evaluation.

Saturated Five-Membered Thiazolidines and Their Derivatives: From Synthesis to Biological Applications

In past decades, interdisciplinary research has been of great interest for scholars. Thiazolidine motifs behave as a bridge between organic synthesis and medicinal chemistry and compel researchers to explore new drug candidates. Thiazolidine motifs are very intriguing heterocyclic five-membered moieties present in diverse natural and bioactive compounds having sulfur at the first position and nitrogen at the third position. The presence of sulfur enhances their pharmacological properties, and, therefore, they are used as vehicles in the synthesis of valuable organic combinations. They show varied biological properties viz. anticancer, anticonvulsant, antimicrobial, anti-inflammatory, neuroprotective, antioxidant activity and so on. This diversity in the biological response makes it a highly prized moiety. Based on literature studies, various synthetic approaches like multicomponent reaction, click reaction, nano-catalysis and green chemistry have been employed to improve their selectivity, purity, product yield and pharmacokinetic activity. In this review article, we have summarized systematic approaches for the synthesis of thiazolidine and its derivatives, along with their pharmacological activity, including advantages of green synthesis, atom economy, cleaner reaction profile and catalyst recovery which will help scientists to probe and stimulate the study of these scaffolds.

Dual inhibitors of hepatitis C virus and hepatocellular carcinoma: Design, synthesis and docking studies

Aim: Simultaneous inhibition of hepatitis C virus (HCV) and hepatocellular carcinoma (HCC) may enhance anti-HCV effects and reduce resistance and side effects. Results/methodology: Novel hybrid derivatives were designed and synthesized to exhibit dual activity against HCV and its associated major complication, HCC. The synthesized compounds were screened for their potential activity against HCV and HCC. Compounds 5f, 5j, 5l, 5p, 5q, 5r, 6c and 6d exhibited potential in vitro anticancer activity against HCC cell line HepG2, while compounds 5a, 5l, 5p and 5v showed in vitro anti-HCV activity. Docking studies suggested that the newly synthesized compounds could suppress HCC through VEGFR2 tyrosine kinase inhibition. Conclusion: Compounds 5l and 5p exhibited dual activity against HCV and HCC in vitro.

Assessing stereoelectronic effects in dipolar cycloadditions yielding fused thiazolopyridone rings

We report a combined experimental and computational study on the cycloadditions of bicyclic 1,3-thiazolium-4-olates, derived from thiazolidin-2-thiones, with asymmetrically-substituted acetylenes. These results provide further mechanistic insights into the above dipolar cycloadditions and enable an unequivocal characterization by NMR spectroscopy of regiochemical patterns as previous derivatives had substituents at both C-2 (in the dipole) and C-6 (in products). Accordingly, new dihydrothiazolopyrid-2-ones have been obtained from a thioisomuenchnone lacking substitution at C-2. With the aim of assessing the steric hindrance as well as the facial stereoselection induced by a bulky group on the Si face (relative to C-7a) of the mesoionic heterocycle, a chiral thioisomuenchnone has also been obtained along with the resulting optically active thiazolopyridones. A computational study of these particular cycloadditions, largely based on an NBO analysis, allowed us to evaluate the influence of substituents on intermolecular steric repulsions, charge transfers, as well as solvent effects.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 76186-04-4 is helpful to your research. Reference of 76186-04-4
