{We have|We’ve|We’ve got} previously shown that prenyl and aliphatic triazoles are {interesting|fascinating|intriguing|exciting} motifs to prepare new chemical entities for antiparasitic and antituberculosis drug {development|improvement}. {In this|Within this} {opportunity|chance} {a new|a brand new} series of prenyl-1,{2|two},3-triazoles {were|had been|have been} {prepared|ready} from isoprenyl azides and {different|various|distinct|diverse|unique|distinctive} alkynes {looking|searching|seeking|hunting} for new antimalarial drug candidates. The compounds {were|had been|have been} {prepared|ready} by copper(I) catalyzed dipolar cycloaddition {of the|from the|in the|on the|with the|of your} isoprenyl azide equilibrium mixture {providing|supplying|offering|delivering|giving} exclusively 1,4-disubstituted 1,{2|two},3-triazols {in a|inside a|within a} regiospecific {fashion|style}. The {complete|total|full|comprehensive} collection of 64 compounds was tested on chloroquine -sensitive, Sierra Leone (D6), {and the|and also the|as well as the|along with the|plus the} chloroquine-resistant, Indochina (W2), strains of Plasmodium falciparum and {those|these} compounds which {were|had been|have been} not previously reported {were|had been|have been} also tested against Leishmania donovani , the causative agent for visceral leishmaniasis. Thirteen analogs displayed antimalarial activity with IC50 {below|beneath|under} {10|ten} uM, {while|whilst|although|even though|when|though} the antileishmanial activity was {less|much less|significantly less} potent than the previously reported analogs. The cytotoxicity assay against Vero cells revealed that none {of the|from the|in the|on the|with the|of your} compounds was cytotoxic {up to|as much as} concentrations of {4|four}.75 ug/mL. Compounds 1o and 1r {were|had been|have been} identified {as the|because the} most promising antimalarial drug leads with IC50 {below|beneath|under} {3|three}.0 uM for {both|each} CQ-sensitive and resistant P. falciparum strains. {Finally|Lastly|Ultimately}, a chemoinformatic in silico {analysis|evaluation} was performed to evaluate physicochemical parameters, cytotoxicity {risk|danger|threat} and drug score. The validation of a bifunctional farnesyl/geranylgeranyl diphosphate synthase PfFPPS/GGPPS {as the|because the} {potential|possible|prospective} target {of the|from the|in the|on the|with the|of your} antimalarial activity of {selected|chosen} analogs {should be|ought to be|needs to be|must be|really should be|need to be} {further|additional} investigated.
