DHODH-IN-14 is a hydroxyfuran analog of A771726, which contains a biphenyl scaffold with a fluorine substituent. Turning to the derivative DHODH-IN-14, no major differences were observed between the poses obtained on 1UUO and 1D3G. In both cases, it was found that DHODH-IN-14 was bound in a BQN-like manner, that is, the deprotonated hydroxyfuran part faced Arg136, thus effectively mimicking the carboxyl groups of BQN and related compounds. Although it was not found on 1D3G and 1UUO that hydroxyfuran interacted with Tyr356 in a similar way to leflunomide, when 2BXV was used as a docking target, a large portion of such postures were found[1].
