Identification of a 4-fluorobenzyl l-valinate amide benzoxaborole (AN11736) as a potential development candidate for the treatment of Animal African Trypanosomiasis (AAT)
摘要:
Novel L-valinate amide benzoxaboroles and analogues were designed and synthesized for a structure-activity-relationship (SAR) investigation to optimize the growth inhibitory activity against Trypanosoma congolense (T. congolense) and Trypanosoma vivax (T. vivax) parasites. The study identified 4-fluorobenzyl (1-hydroxy-7-methyl-1,3-dihydrobenzo[c][1,2] oxaborole-6-carbonyl)-L-valinate (5, AN11736), which showed IC50 values of 0.15 nM against T. congolense and 1.3 nM against T. vivax, and demonstrated 100% efficacy with a single dose of 10 mg/kg against both T. congolense and T. vivax in mouse models of infection (IP dosing) and in the target animal, cattle, dosed intramuscularly. AN11736 has been advanced to early development studies. (C) 2017 The Authors. Published by Elsevier Ltd.

VersatAAIL Surfactants: Biodegradable, chiral aminoacidionicliquidsurfactants (AAILSs) with a very high surface activity are synthesized and characterized. The AAILS can be applied as task‐specific ionicliquids; two examples given are the mitigation of harmful algal blooms from sea water and the shape‐ and size‐specific synthesis of nanomaterials.
