Medicinal plants play a vital role for the development of new drugs. The bioactive extract should be standardized on basis active compound. undergo safety studies. Almost, 70% modern medicines in India are derived from natural products. central not only as traditional but also trade commodities, meeting demand distant markets. Camphor is familiar to many people principal ingredient topical home remedies wide range symptoms, and its use well consolidated among population whole world, having...
Bifunctionalized indoles are an important class of biologically active heterocyclic compounds and potential drug candidates. Because the lack efficient synthetic methods, one pot cascade synthesis these is rare remains a challenge. To expand this field, we herein disclose step-economical temperature tunable strategy wherein synergistic effect between [hmim]Br-ArSO2Cl leads exclusively to formation 3-arylthio indole via sulfenylation at room temperature, while heating reaction mixture 50 °C...
Arsenic trioxide (ATO/As2O3) is a promising drug for patients with relapse of acute promyelocytic leukemia (APL); however, it frequently causes fatal arrhythmias. This study aims to investigate the various cellular and molecular mechanisms adverse cardiac effects electrophysi-ological alterations caused by As2O3. We show dose-dependent effect ATO (0.2, 0.4, 0.8, 1.6, 3.2, 6.4 mum) on electrically driven action potential from papillary muscle guinea pig. significant prolongation duration...
Abstract A direct, new and eco-friendly strategy for the one-step synthesis of methoxylated hydroxylated styrenes from β-(phenyl)-β-(phenylthio)propionic acids is reported. This approach utilizes a neutral ionic liquid [hmim]Br-triggered cascade decarboxylative dehydrosulfenylation reaction under microwave irradiation, without need strong bases, toxic metal oxidants, eliminates phenolic group protection–deprotection strategy, thus offering an efficient route to bio-based commercially...
Non-prescription drugs are that can be purchased without a doctor's prescription, which obtained at pharmacies, drug stores, or even on e-commerce. In the digitalization era of 21st century, technological progress is increasingly rapid, where all aspects human life now dependent function each type technology. Traditional marketing activities being innovated in digital to become using social media influencers. This research aims see influence SMI Characteristics and Brand Congruence...
Abstract The synergistic combination of two catalysts is an emerging strategy towards the formation unprecedented complex molecules, and herein bovine serum albumin (BSA) neutral ionic liquid 1‐butyl‐3‐methylimidazolium bromide ([bmim]Br) are used together for first time multiple C−C C−S bond‐formation reactions in one pot under metal‐free, acid‐free, base‐free conditions by merging classical named reactions, that is, aldol condensation (AC) thia‐Michael addition (TMA) cascade chemoselective...
An efficient dual Pd-catalytic system was developed for one-pot synthesis of 3-sulfenylindoles via C-C, C-N and C-S bond construction directly from unactivated 2-iodo(NH)anilines under mild reaction conditions. Furthermore, 3-selenyl/halo/carbon-functionalized indoles were synthesized in good yields a short time. The synthetic utility 3-sulfenylindole also demonstrated. key role solvent palladium catalysis unravelled by DFT.
Abstract For over a decade, ionic liquids have been recognized as green solvents and/or catalysts in the chemical world owing to their unique physical/chemical properties resulting diverse range of and biochemical transformations. One striking features is ability act an ambiphilic catalyst i. e. dual electrophilic‐nucleophilic activation substrate. The complex interplay hydrogen bonding, Coulomb Van‐der Waals interactions between cationic anionic part liquid imparts this ambiphilicity...
The assembly processes that underlie the composition and connectivity of free-living (FL) particle-associated (PA) bacterial communities from surface to deep waters remain little understood. Here, using phylogenetic null modeling, we quantify relative influence selective stochastic mechanisms assemble FL PA throughout water column in a high Arctic fjord. We demonstrate acting on are similar waters, but become increasingly distinct waters. As depth increases, homogeneous selection increases...
Abstract In this report, a synergistic combination of L‐arginine and [bmim]Br has been realized for the first time towards step‐economical synthesis β‐aryl‐β‐sulfanyl esters from aromatic aldehyde, malonate thiol via cascade thia‐Michael addition reaction on in situ formed unactivated β‐aryl‐α,β‐unsaturated (via decarboxylative Knoevenagel reaction) under metal‐and acid/base‐free conditions. Furthermore, gram scalability recyclability catalytic system (up to 5 cycles) makes our one‐pot...
Urban lakes play a major role in the socio-cultural and ecological sustainability of many cities, but are often under development pollution pressures. decision makers faced with challenging task identifying causes their decline building plans for conservation or rejuvenation. Powai Lake is perfect example an urban water body historic, cultural, importance to population Metropolitan Mumbai, local regional authorities, including Development Department, Government Maharashtra, working identify...
Abstract A neutral ionic liquid, [hmim]Br, catalyzed the direct dehydrosulfenylation of β‐sulfido carbonyl compounds under microwave irradiation into corresponding α,β‐unsaturated with exclusive trans selectivity in one pot. This procedure improves on conventional routes, which require an additional step for oxidation sulfoxides/sulfones prior to presence a metal catalyst/oxidant or base/acid catalyst. Notably, this step‐economical and waste‐free has also been extended generation ( E...
