PG - 4342-50 LID - S0968-0896(13)00379-9 [pii] LID - 10.1016/j.bmc.2013.04.053 [doi] AB - Many synthetic retinoids contain an aromatic structure with a bulky hydrophobic fragment. In order to obtain retinoids with therapeutic potential that do not bind to or activate retinoic acid X receptors (RXRs), we focused on the introduction of novel hydrophobic moieties, that is, metacyclophane, phenalene and benzoheptalene derivatives. The designed compounds were synthesized and their agonistic activities towards RARs and RXRs were evaluated. Most of the active compounds showed selectivity for RARalpha and RARbeta over RARgamma, and higher RARbeta transactivating activity seemed to correlate with higher cell differentiation-inducing activity towards promyelocytic leukemia cell line HL-60. These compounds showed no agonistic activity towards RXRs. CI - Copyright (c) 2013 Elsevier Ltd. All rights reserved.
