Chagas Disease Drug Discovery: Multiparametric Lead Optimization against Trypanosoma cruzi in Acylaminobenzothiazole Series

Acylaminobenzothiazole hits were identified as potential inhibitors of Trypanosoma cruzi replication, a parasite responsible for Chagas disease. We selected compound 1 for lead optimization, aiming to improve in parallel its anti-T. cruzi activity (IC50 = 0.63 μM) and its human metabolic stability (human clearance = 9.57 mL/min/g). A total of 39 analogues of 1 were synthesized and tested in vitro. We established a multiparametric structure-activity relationship, allowing optimization of antiparasite activity, physicochemical parameters, and ADME properties. We identified compound 50 as an advanced lead with an improved anti-T. cruzi activity in vitro (IC50 = 0.079 μM) and an enhanced metabolic stability (human clearance = 0.41 mL/min/g) and opportunity for the oral route of administration. After tolerability assessment, 50 demonstrated a promising in vivo efficacy.

Preparation method of 3-oxetanecarboxylic acid

The invention provides a preparation method of 3-oxetanecarboxylic acid. According to the preparation method, 2-hydroxymethyl-2-nitro-1,3-propylene glycol is taken as a raw material, hydroxyl in 2-hydroxymethyl-2-nitro-1,3-propylene glycol is subjected to a group protection reaction, nitryl in 2-hydroxymethyl-2-nitro-1,3-propylene glycol is subjected to a reductive elimination reaction and hydrolysis reaction, and 2-hydroxymethyl-1,3-propylene glycol is obtained; 2-hydroxymethyl-1,3-propylene glycol is continuously subjected to a cyclization reaction and an oxidation reaction, and 3-oxetanecarboxylic acid is obtained. The provided preparation method can be completed only through five-step reactions; compared with existing preparation methods through ten-step reactions, the preparation method has the advantages that the reaction steps are greatly reduced, the reaction routes are greatly shortened, the overall yield is increased, and the final yield can be up to 50% or above on the basisof the raw material, namely, 2-hydroxymethyl-2-nitro-1,3-propylene glycol; the related reactions are simple, and the method is easy to operate and favorable for industrial production.

Preparation method of 3-oxetane carboxylic acid

The invention provides a preparation method of 3-oxetane carboxylic acid. The preparation method is characterized by carrying out hydrolytic esterification reaction, hydrogen pulling reaction and reduction reaction by taking 3-hydroxypropionitrile as a raw material, thus obtaining 2-benzyloxymethyl-1,3-propanediol; carrying out cyclization reaction, debenzylation reaction and oxidation reaction on2-benzyloxymethyl-1,3-propanediol, thus obtaining 3-oxetane carboxylic acid. According to the preparation method of 3-oxetane carboxylic acid, provided by the invention, a key intermediate 2-benzyloxymethyl-1,3-propanediol can be prepared just through three-steps reaction by taking 3-hydroxypropionitrile as the raw material, and 3-oxetane carboxylic acid can be prepared just through six-steps reaction in a final integral route, so that the reaction route is greatly shortened, and reaction steps are reduced; compared with a preparation method requiring ten-steps reaction in the prior art, theyield is higher, the operation is easy, and industrial production can be favorably realized.
