To derive new uricosuric agents, novel phenol derivatives were synthesized to overcome the disadvantages of benzbromarone (BBR), attributed by its structural features. Herein, we report the discovery of new phenol derivatives with a 1,1-dioxo-1,2-dihydro-3H-1,3-benzothiazole scaffold. The selected compound 11 (dotinurad, FYU-981) demonstrated remarkable inhibitory activity on uric acid uptake by primary
Disclosed are a novel compound and a pharmaceutical product, each having a remarkable uricosuric effect. Specifically disclosed are: a novel phenol derivative represented by general formula (1) that is shown in FIG. 1; a pharmaceutically acceptable salt thereof; a hydrate of the derivative or the salt; and a solvate of the derivative or the salt. (In the formula, R1 and R2 may be the same or different and each represents a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a lower alkoxy group, a haloalkyl group, a haloalkoxy group, an alkylsulfanyl group, an alkylsulfinyl group, an alkylsulfonyl group, a lower alkyl-substituted carbamoyl group, a saturated nitrogen-containing heterocyclic N-carbonyl group, a halogen atom, a cyano group or a hydrogen atom; R3 represents a lower alkyl group, a haloalkyl group, a halogen atom, a hydroxy group or a hydrogen atom; and X represents a sulfur atom, an —S(═O)— group or an —S(═O)2— group.)

The present invention relates to pharmaceutical compounds, compositions, combinations, and methods, especially as they are related to compositions and methods for the treatment and/or prevention of conditions such as gout that are associated with excessive levels of uric acid. The invention provides compounds of Formula (I) as further described herein, which inhibit activity of urate reabsorption transporter 1 (URAT1, also known as SLC22A12). The compounds are useful to treat conditions associated with excessive levels of uric acid, such as gout.
