2-[(1,3-Benzothiazol-2-yl)iminomethyl]-6-methoxyphenol: a new monoclinic polymorph
The title compound, C15H12N2O2S, is a P21/c polymorph of a previously reported P21/n polymorph [Büyükgüngör et al. (2004 ▶). Acta Cryst. E60, o1414-o1416]. The dihedral angle between the benzo-thia-zole (r.m.s. deviation = 0.010 Å) and the benzene ring of 7.86 (6)° compares with 10.76 (10)° in the literature structure. The meth-oxy substituent is almost coplanar with the benzene ring to which i...
متن کاملThe cardioprotective effects of 4-O-(2″-O-acetyl-6″-O- p-coumaroyl-β-D-glucopyranosyl)-p-coumaric acid (4-ACGC) on chronic heart failure
The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in vivo and in vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (...

متن کامل(2R)-2-Benzenesulfonamido-2-phenylethanoic acid: a new monoclinic polymorph
In the title compound, C(14)H(13)NO(4)S, a sulfonamide derivative of phenyl glycine, the aromatic rings are inclined at a dihedral angle of 28.03 (12)°. In the crystal, O-H⋯O hydrogen bonds link the molecules into chains propagating in [100] and a weak C-H⋯O interaction cross-links the chains in the c-axis direction. In the previously published polymorph, the dihedral angle between the aromatic...
متن کاملA second polymorph of β-arteether
The crystal structure of the title compound, C(17)H(28)O(5), reported here is a polymorph of the structure first reported by El-Feraly, Al-Yahya, Orabi, McPhail & McPhail [J. Nat. Prod. (1992). 55, 878-883]. It is a derivative of the anti-malaria compound artemisinin and consists primarily of three substituted ring systems fused together. A cyclo-hexane ring (distorted chair conformation) fused...
