Addition of a sterically demanding cyclic (alkyl)(amino)carbene (CAAC) to AuCl(SMe 2 ) followed by treatment with [Et 3 Si(Tol)] + [B(C 6 F 5 4 ] − in toluene affords the isolable [(CAAC)Au(η -toluene)] complex. This cationic Au(I) complex efficiently mediates catalytic coupling enamines and terminal alkynes yield allenes not propargyl amines as observed other catalysts. Mono-, di-, tri-substituted can be used, well aryl-, alkyl-, trimethylsilyl-substituted alkynes. The reaction tolerates...
Abstract Two very distinct chemical reactions, yet a single catalyst : A gold complex promotes the formation of tertiary enamines from variety terminal and internal alkynes. Subsequent addition alkyne to reaction mixture affords allenes (see scheme). magnified image
Traditional ecological knowledge, linguistic, and sociocultural perspectives are key contributors to environmental sustainability. Therefore, it is essential identify preserve this biocultural heritage, especially that of indigenous communities minorities. We conducted an ethnobotanical survey document the plant species used by Balti Shina living in buffer zone Deosai National Park (DNP), western Himalayas, Pakistan. A combination random purposive sampling techniques was adapted, targeting...
The present study reports a convenient approach for the synthesis of thiophene sulfonamide derivatives (3a–3k) via Suzuki cross coupling reaction. This method involved reactions various aryl boronic acids and esters with 5-bromthiophene-2-sulfonamide (2) under mild suitable temperature conditions. compounds synthesized in were subjected to urease inhibition hemolytic activities. substitution pattern electronic effects different functional groups (i.e., Cl, CH3, OCH3, F etc.) available on...
In general, benzothiazole derivatives have attracted great interest due to thier pharmaceutical and biological importance. New 2-amino-6-arylbenzothiazoles were synthesized in moderate excellent yields via Suzuki cross coupling reactions using various aryl boronic acids acid pinacol esters the antiurease nitric oxide (NO) scavenging activity of products also examined. The most active compound concerning urease enzyme inhibition was 6-phenylbenzo[d]thiazole-2-amine 3e, with an IC50 value...

Background: Traditional medicines knowledge is more famous and well-documented in rural remote areas Pakistan worldwide than urban areas. A present effort was made to document the ethnobotanical practices among communities of Karachi city provide basis for development natural drug discovery. Methods: For data collection, 177 local informants traditional healers were interviewed. Various quantitative indices such as relative frequency citation (RFC), fidelity level (FL), use value (UV),...
A new COVID-19 variant, Omicron, has emerged from South Africa, indicating that the pandemic will not be over anytime soon. An unimaginable amount of economic damage resulted pandemic. Omicron and its implications are discussed in detail this review article. It also includes statistics on occurrence, mortality, recuperation Pakistan data country’s immunization coverage. Developing countries with unstable economies, such as Pakistan, have experienced increased difficulties. As a result, all...
Abstract The current paper elaborates the wild edible plants’ (WEPs) diversity, and associated traditional knowledge among three ethnic groups of Balochistan Province, Pakistan. field trips were carried out in 2018-2020 employing purposive sampling techniques for respondents. We used open ended semi-structured interviews data collection. A total 195 reported 140 plant species 44 families 105 genera. Family Brassicaceae (10.17%) showed maximum representation along with Asteraceae (10%),...
Abstract Traditional medicine uses and knowledge is more famous well documented in rural/remote areas Pakistan worldwide than the urban areas. The present effort was made to document ethnomedicinal practices among communities of Karachi city provides basis for development natural drug discovery. We are aware no other quantitative ethnobotanical investigation on use medicinal plants study area prior this study. For data collection, 177 local informants traditional healers were interviewed,...

Abstract The carbazoles are synthesized from L‐menthone and substituted phenyl hydrazines in acetic acid show promising inhibitory activities against acetyl‐ butyrylcholinesterase.
This research work entails the synthesis of transition metal complexes with methyl and methoxy aminoaryl derivatives. All ligands were synthesized from readily available benzisothiazole. Various solvent systems, under different sets reaction conditions tried to develop a method for complex formation. Methanol was proved be best complexation. The newly methodology then applied which identified by spectroscopic techniques. structural assignments, carried out studies. Conclusively, higher...

Despite massive efforts to protect plant diversity around the world over last few decades, it is becoming increasingly evident that present policies are insufficient prevent continued trends of decline in biodiversity.The encroachment humans and their animals on protected areas causing changes its natural environment.This study was performed highlands Sra Ghurgai, Quetta District, Balochistan from July November 2020.The used a survey approach included purposive location selection,...
