Agonism of S1P1 receptor has been proven to be responsible for peripheral blood lymphopenia and elicits the identification of various S1P1 modulators. In this paper the authors described a series of oxadiazole-based S1P1 direct-acting agonists disubstituted on terminal benzene ring, with high potency for S1P1 receptor and favorable selectivity against S1P3 receptor. In addition, two representative agents named I and II demonstrated impressive efficacy in lymphocyte reduction along with reduced effect on heart rate when orally administered. Furthermore, these compounds have been shown to possess desired pharmacokinetic (PK) and physicochem. profiles. The binding mode between I and the activated S1P1 model was also studied.

The article was titled 《A new, substituted palladacycle for ppm level Pd-catalyzed Suzuki-Miyaura cross couplings in water》. The information in the text is summarized as follows:

A newly engineered palladacycle that contains substituents on the biphenyl rings along with the ligand HandaPhos is especially well-matched to an aqueous micellar medium, enabling valued Suzuki-Miyaura coupling of aryl halides RX (R = 2-O2NC6H4, 1-benzothiophen-2-yl, 2-fluoropyridin-3-yl, etc.; X = Cl, Br, I) and aryl boronic acids R1B(OH)2 (R1 = 4-ClC6H4, 1-benzofuran-2-yl, pyren-1-yl, etc.) to be run not only in water under mild conditions, but at 300 ppm of Pd catalyst. This general methodol. has been applied to several targets in the pharmaceutical area. Multiple recyclings of the aqueous reaction mixture involving both the same as well as different coupling partners are demonstrated. Low temperature microscopy (cryo-TEM) indicates the nature and size of the particles acting as nanoreactors. Importantly, given the low loadings of Pd invested per reaction, ICP-MS analyses of residual palladium in the products show levels to be expected that are well within FDA allowable limits.

The information in the text is summarized as follows:

The synthesis of the asym. ligand 3-phenyl-1-(pyridin-2-yl)-1H-pyrazol-5-amine (L1) and its single-crystal X-ray structure are reported. L1 displays crystallog. symmetry (orthorhombic, Pccn) higher than its mol. symmetry (point group C1) and also displays supercooling, with a difference in the melting and solidification points of over 100°C. Upon complexation with ZnCl2, L1 engages in both primary cation and secondary anion coordination via hydrogen bonding, and the complex exhibits a room-to-low-temperature single crystal-to-crystal phase transition. The ZnCl2 complex becomes a birefringent fluid mixed with crystalline domains at high temperatures, as detected by polarized optical microscopy. Examination of the photoluminescence properties showed that the emission intensity increased and a pronounced bathochromic shift was observed in the emission maximum upon going from solution to the solid state, for both the ligand and complex, consistent with aggregation-induced emission behavior. The syntheses and single-crystal structures of 3-phenyl-1-(pyridin-2-yl)-1H-pyrazol-5-amine (L1) and its complex with ZnCl2 are reported. L1 exhibits supercooling, with a difference in the melting and solidification points of over 100°C. The complex [L1ZnCl2] has a room-to-low-temperature single crystal-to-crystal phase transition in the solid state, while a birefringent fluid phase mixed with crystalline domains is present at high temperatures Significant fluorescence enhancement is observed upon formation of the ZnCl2 complex.

SDS of cas: 2042-37-7 The author mentioned the following in the article:

A general method is described for the coupling of (hetero)aryl bromides with O-alkyl sulfamate esters. The protocol relies on catalytic amounts of nickel and photoexcitable iridium complexes and proceeds under visible light irradiation at ambient temperature This technol. engages a broad range of simple and complex O-alkyl sulfamate ester substrates under mild conditions. Furthermore, it is possible to avoid undesirable N-alkylation, which was found to plague palladium-based protocols for N-arylation of O-alkyl sulfamate esters. These investigations represent the first use of sulfamate esters as nucleophiles in transition metal-catalyzed C-N coupling processes.
