Structural Basis for Developing Multitarget Compounds Acting on Cysteinyl Leukotriene Receptor 1 and G-Protein-Coupled Bile Acid Receptor 1

G-protein-coupled receptors (GPCRs) are the molecular target of 40% of marketed drugs and the most investigated structures to develop novel therapeutics. Different members of the GPCRs superfamily can modulate the same cellular process acting on diverse pathways, thus representing an attractive opportunity to achieve multitarget drugs with synergic pharmacological effects. Here, we present a series of compounds with dual activity toward cysteinyl leukotriene receptor 1 (CysLT1R) and G-protein-coupled bile acid receptor 1 (GPBAR1). They are derivatives of REV5901-the first reported dual compound-with therapeutic potential in the treatment of colitis and other inflammatory processes. We report the binding mode of the most active compounds in the two GPCRs, revealing unprecedented structural basis for future drug design studies, including the presence of a polar group opportunely spaced from an aromatic ring in the ligand to interact with Arg792.60 of CysLT1R and achieve dual activity.

Phthalocyanine-based discotic liquid crystals switching from a molten alkyl chain type to a flying-seed-like type

We have synthesised a series of phthalocyanine-based discotic liquid crystals, (m-CnOPhO)8PcCu (n = 1-20: 2a-o), and investigated their mesomorphism by using a polarizing optical microscope (POM), a differential scanning calorimeter (DSC) and a temperature-dependent small angle X-ray diffractometer. We found that each of the derivatives 2a-o shows mesomorphism. However, the mesomorphism of the (m-CnOPhO)8PcCu derivatives strongly depends on the alkoxy chain length (n). The mesomorphism of the short chain-substituted derivatives 2a-e for n = 1-5 is a flying-seed-like type induced by flip-flop of the peripheral bulky substituents, whereas the mesomorphism of the long chain-substituted derivatives 2j-o for n = 10-20 is a conventional molten alkyl chain type induced by melting of the long alkyl chains. The moderately long chain derivatives (2f-i) for n = 6-9 in between show both types of mesophases. The detailed temperature-dependent X-ray diffraction measurements were carried out for three representative derivatives, 2b (n = 2 for n = 1-5), 2h (n = 8 for n = 6-9), and 2o (n = 20 for n = 10-20). As a result, we revealed that the Colro(P2m) mesophase in 2b (n = 2) gave a halo denoted as Haloarom. at d ? 5.2 ? due to flip-flop of the bulky aromatic substituents, and that the Colho mesophase in 2o (n = 20) gave a halo denoted as Haloalkyl at d ? 4.6-4.8 ? due to melting of the long alkyl chains. Therefore, we can distinguish the type of mesophase from Haloarom. and Haloalkyl. Very interestingly, the (m-C8OPhO)8PcCu (2h) derivative having moderately long alkyl chains gave Haloalkyl at about 4.8 ? in the lower temperature mesophase of Colho, but Haloarom. at about 5.2 ? in the higher temperature mesophase of Colro(P21/a). This means that melting of the alkyl chains induces the Colho phase in the lower temperature region, but that flip-flop of the bulky aromatic substituents induces the Colro(P21/a) phase in the higher temperature region. This unusual reverse phase transition sequence from a higher symmetry of the Colh mesophase to a lower symmetry of the Colr mesophase on a heating stage is attributable to such a unique stepwise melting of these two different types of substituents. To the best of our knowledge, this mesogen (2h) is the first example switching mesomorphism from the molten alkyl chain type to the flying-seed-like type in a discotic liquid crystal.
