Research ArticleOpen accessIn the abstractComputer Aid Screening for Potential Antimalarial Choroquinone Compounds as Covid 19 Utilizing Computational Calculations and Molecular Docking StudyAsmaa Aboelnaga, Asmaa M. Fahim, Taghreed H. EL-SayedClick reaction of 4,7-dichloroquinoline (1) with thiosemicarbazide (2) to afford the corresponding 2-(7-chloroquinolin-4-yl)thiosemicarbazide (3) utilized ultrasonic irradiation which can cyclized easily with ethylacetoacetate to give the 3-(7-chloroquinolin-4-ylamino)-tetrahydro-6-methyl-2-thioxopyrimidin-4(1H)-one (4) via nucleophilic substitution reaction. The synthesized compounds was examined in vitro antimalarial activity with IC50 = 11.92, 25.37 μg/mL against chloroquinone drug. Furthermore, the theoretical investigation of most active compounds CQT and … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 30 Nov 2020 · 6,570 accessesView PDFCite

Research ArticleOpen accessIn the abstractDiversity and Allelopathic Potential of Weeds among Panamanian Coffee CropsLilia Cherigo, Jorge Lezcano, Sergio Martínez-LuisWorldwide, coffee is one of the most highly consumed and produced crops. Coffee production is a significant activity in the Panamanian economy, mainly in rural communities and among indigenous groups in the Chiriquí province highlands. Weeds growing alongside coffee plants can provoke considerable economic losses for producers by interfering with the growth, development and yield of coffee crop in cultivated … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 6 Sep 2017 · 7,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Heavy Metals on the Enzymatic Activity of Haplic Chernozem under Model Experimental ConditionsNatalia Gromakova, Saglara Mandzhieva, Tatiana Minkina et al.The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Jul 2017 · 7,996 accessesView PDFCite
