8-O-Azeloyl-14-benzoylaconine: a new alkaloid from the roots of Aconitum karacolicum Rapcs and its antiproliferative activities.
A new alkaloid of Aconitum karacolicum Rapcs, from the Ranunculaceae family, collected in Kirghizstan, was isolated from the roots of this plant, using a purification scheme based upon its in vitroExpand
Synthesis of Omeprazole Analogues and Evaluation of These as Potential Inhibitors of the Multidrug Efflux Pump NorA of Staphylococcus aureus
A structure-activity relationships study identified the benzimidazole nucleus of omeprazole as the main structural element involved in efflux pump inhibition and highlighted the critical role of the chlorine substituents in the stability and efficiency of compounds 1e to 1f. Expand
New ferrocenic pyrrolo[1,2-a]quinoxaline derivatives: synthesis, and in vitro antimalarial activity--Part II.
Novel series of ferrocenyl-substituted pyrrolo[1,2-a]quinoxalines 1-2 were synthesized from ferrocene-carboxaldehyde and tested for their in vitro activity upon the erythrocytic development of Plasmodium falciparum strains with different chloroquine-resistance status. Expand
Converting potent indeno[1,2-b]indole inhibitors of protein kinase CK2 into selective inhibitors of the breast cancer resistance protein ABCG2.
It was possible to convert, through suitable substitutions of the indeno[1,2-b]indole-9,10-dione scaffold, potent CK2 inhibitors into selective ABCG2 inhibitors and vice versa. Expand
Antispasmodic and antioxidant activities of fractions and bioactive constituent davidigenin isolated from Mascarenhasia arborescens.
The main objective of this work was to evaluate the antispasmodic activity of the crude methanolic extract of Mascarenhasia arborescens and of its four partitions and to identify the effective compound responsible for this effect. Expand
Synthesis and preliminary evaluation of new ursolic and oleanolic acids derivatives as antileishmanial agents
A series of new ursolic and oleanolic acids derivatives was synthesized via ursolic or oleanolic acids, previously extracted from South American Ilex species. These new compounds were tested for inExpand
Synthesis and PreliminaryIn Vitro Evaluation of Antimycobacterial Activity of New Pyrrolo[1,2-a]quinoxaline-carboxylic Acid Hydrazide Derivatives
New pyrrolo[1,2-a]quinoxaline-2- or -4-carboxylic acid hydrazide derivatives were synthesized from nitroaniline or 1,2-phenylenediamine, and evaluated in vitro for their antimycobacterial activity asExpand
Synthesis, antimalarial activity, and molecular modeling of new pyrrolo[1,2-a]quinoxalines, bispyrrolo[1,2-a]quinoxalines, bispyrido[3,2-e]pyrrolo[1,2-a]pyrazines, and
A possible mechanism of interaction implicating binding of pyrroloquinoxalines to beta-hematin was supported by molecular modeling and it was observed that the presence of a methoxy group on the p Pyrrolo[1,2-a]quinoxaline nucleus increased the pharmacological activity. Expand
Synthesis and preliminary evaluation of new 1- and 3-[1-(2-hydroxy-3-phenoxypropyl)]xanthines from 2-amino-2-oxazolines as potential A1 and A2A adenosine receptor antagonists.
A new synthetic access to racemic xanthine derivatives 1-4 from 5 is presented, and their evaluation as adenosine A1, A2A and A3 receptor ligands in radioligand binding studies are presented. Expand
