Synthesis and evaluation of a 2-benzothiazolylphenylmethyl ether class of histamine H4 receptor antagonists

Bioorg Med Chem Lett. 2016 Nov 1;26(21):5263-5266. doi: 10.1016/j.bmcl.2016.09.049. Epub 2016 Sep 19.

Abstract

Synthesis and biological evaluation of a new class of histamine H4 receptor ligands, distinct from the previously reported chemotypes, are described. A virtual screening of our corporate compound collection identified a hit with an undesired dual H3R/H4R activity. Chemical exploration led to the discovery of a more potent and selective 2-benzothiazolylphenylmethyl ether lead compound.

Keywords: Asthma; Atopic dermatitis; Histamine; Histamine H(4) receptor.
