Design, Synthesis, and Antiprotozoal Evaluation of New Promising 2,9-Bis[(substituted-aminomethyl)]-4,7-phenyl-1,10-phenanthroline Derivatives, a Potential Alternative Scaffold to Drug Efflux

Pathogens, 2022
A series of novel 2,9-bis[(substituted-aminomethyl)]-4,7-phenyl-1,10-phenanthroline derivatives was designed, synthesized, and evaluated in vitro against three protozoan parasites (Plasmodium falciparum, Leishmania donovani and Trypanosoma brucei brucei).

Preparation and antitrypanosomal activity of secochiliolide acid derivatives

Bioorganic & Medicinal Chemistry Letters, 2013
Secochiliolide acid (1) isolated from the Patagonian shrub Nardophyllum bryoides, was used as a scaffold for the preparation of a series of nine derivatives. Compound 1 and its derivatives were tested against Trypanosoma cruzi epimastigotes grown in liquid media.

Pyridyl‐Imidazopyridine Derivatives Displaying Submicromolar Activity Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Previously reported pyridyl‐thiazoles and highly active imidazopyridines against Trypanosoma cruzi inspired the design of a new series of pyridyl‐substituted imidazopyridines. Among the synthesized compounds, 5h emerged as the most promising derivative, displaying potent trypanocidal activity (EC50 = 0.16 μM), excellent selectivity (SI > 1250), and ...

Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

Applied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Manganese Porphyrin‐Catalyzed One‐Pot Oxidation of Lupeol: Efficient Conversion of Its Terminal Alkene Into Carboxylic Acids

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Manganese porphyrin catalyst enables green PhI(OAc)2 oxidation of lupeol in ethyl acetate, achieving 94% conversion and the formation of eight products, including selective C20 olefin transformations and one‐pot conversion of the isopropenyl group to carboxylic acids, all without the need of C3‐OH protection step.
