Both N- and T-type calcium ion channels have been implicated in pain transmission and the N-type channel is a well-validated target for the treatment of neuropathic pain. An SAR investigation of a series of substituted aminobenzothiazoles identified a subset of five compounds with comparable activity to the positive control Z160 in a FLIPR-based intracellular calcium response assay measuring potency at both Ca_V2.2 and Ca_V3.2 channels. These compounds may form the basis for the development of drug leads and tool compounds for assessing in vivo effects of variable modulation of Ca_V2.2 and Ca_V3.2 channels.

氨基苯并噻唑作为N型和T型钙通道阻滞剂的合成与评价

N型和T型钙离子通道均与疼痛传递有关，并且N型通道是治疗神经性疼痛的有效靶点。对一系列取代的氨基苯并噻唑的SAR研究在基于FLIPR的细胞内钙反应测定法中测定了在Ca _V 2.2和Ca _V 3.2通道的效价，确定了与阳性对照Z160具有可比活性的五种化合物的子集。这些化合物可能构成开发药物前导和工具化合物的基础，这些化合物和工具化合物用于评估Ca _V 2.2和Ca _V 3.2通道的可变调节的体内作用。
