And the article contained the following:
The C-C chemokine receptor 4 (CCR4) is broadly expressed on regulatory T cells (Treg) as well as other circulating and tissue-resident T cells. Treg can be recruited to the tumor microenvironment (TME) through the C-C chemokines CCL17 and CCL22. Treg accumulation in the TME has been shown to dampen the antitumor immune response and is thought to be an important driver in tumor immune evasion. Preclin. and clin. data suggest that reducing the Treg population in the TME can potentiate the antitumor immune response of checkpoint inhibitors. We have developed small-mol. antagonists of CCR4, featuring a novel piperidinyl-azetidine motif, that inhibit the recruitment of Treg into the TME and elicit antitumor responses as a single agent or in combination with an immune checkpoint blockade. The discovery of these potent, selective, and orally bioavailable CCR4 antagonists(I), and their activity in in vitro and in vivo models, is described herein. The experimental process involved the reaction of tert-Butyl 3-(piperidin-4-yl)azetidine-1-carboxylate(cas: 1251006-64-0).Application In Synthesis of tert-Butyl 3-(piperidin-4-yl)azetidine-1-carboxylate
