A new series of ester analogues of artemisinin 8a–f, incorporating diphenylmethyl as pharmacologically privileged substructure, and 8g–j have been prepared and evaluated for their antimalarial activity against multidrug-resistant (MDR) Plasmodium yoelii nigeriensis in Swiss mice via oral route. These diphenylmethyl-based ester analogues 8a–f were found to be 2–4 folds more active than the antimalarial drugs β-arteether 4 and artesunic acid 5. Ester 8a, the most active compound of the series, provided complete protection to the infected mice at 24?mg/kg?×?4?days as well as 12?mg/kg?×?4?days, respectively. In this model β-arteether provided 100% and 20% protection at 48?mg/kg?×?4?days and 24?mg/kg?×?4?days, respectively.

A series of urea based calcimimetics was optimized for potency and oral bioavailability. Crucial to this process was overcoming the poor pharmacokinetic properties of lead thiazole 1. Metabolism-guided modifications, characterized by the use of metabolite identification (ID) and measurement of time dependent inhibition (TDI) of CYP3A4, were essential to finding a compound suitable for oral dosing. Calcimimetic 18 exhibited excellent in vivo potency in a 5/6 nephrectomized rat model and cross-species pharmacokinetics.
