title: Urate transporter URAT1 inhibitors: a patent review (2012 - 2015).
abstract: Human urate transporter 1 (URAT1, encoded by SLC22A12) has been identified as a key urate transporter expressed at the apical membrane of renal proximal tubule cells for regulating urate homeostasis. Therefore, URAT1 is an attractive target for the development of new uricosurics against hyperuricemia. Discovery of novel inhibitors targeting URAT1 has become a research hotspot in recent years. Areas covered: In this paper, we reviewed the patent applications and related research published during the years 2012-2015, covering the development of URAT1 inhibitors. Expert opinion: There are some promising and inspiring patent applications in this area. Several compounds have superior inhibitory activity of URAT1 with the availability of urate-lowering treatment. For new drug development and commercialization, further studies are needed to evaluate the efficacy and safety.
