  • HY-109513
    Ioxilan

    		Biochemical Assay Reagents Others
    Ioxilan is a low-osmolar, nonionic and tri-iodinated diagnostic contrast agent. Ioxilan is also an X-ray contrast agent for excretory urography and contrast enhanced computed tomographic (CECT) imaging of the head and body. Intravascular injection results in opacification of vessels in the path of flow of the contrast medium, permitting radiographic visualization of the internal structures of the human body until significant hemodilution occurs .

    Semotiadil

    SD-3211

    		 Others Others
    Semotiadil is a novel calcium antagonist whose stereochemical structure was investigated by X-ray crystallography and circular dichroism spectroscopy. X-ray structural analysis was performed using its enantiomeric salts with (S)-(+)-mandelic acid (2); 1 (mandelate salt). The R absolute configuration of 1, which was previously determined by chemical transformation of an optically active synthetic precursor, was directly confirmed by this analysis. Hydrogen bonding, charge repulsion, and hydrophobic interactions that stabilize the crystal structure were observed in the crystals. Circular dichroism spectra of 1 (mandelate salt) and 1 (hydrofuranate salt) in ethanolic solution showed similar spectral patterns. The CD bands of each chromophore were unambiguously assigned, and the conformation of the benzothiazole ring was determined using the optical rotation rule. The X-ray and CD data confirmed the P conformation of the benzothiazole ring and the equatorial position of the 2-phenyl ring in both the crystal and ethanolic solution states. These findings are in good agreement with our previous results on the conformational analysis of 2-arylbenzothiazole derivatives.

    Pyrroxamycin

    Dioxapyrrolomycin; LL-F42248α; AL-R2081

    		 Others Infection
    Pyrroxamycin is a novel antibiotic produced by Streptomyces, whose chemical structure was determined by chemical properties and X-ray crystallography and 13C NMR spectroscopy analysis. It is active against Gram-positive bacteria and dermatophytes. In this paper, the authors discuss the taxonomy, fermentation, isolation, physicochemical properties, chemical structure, and biological activity of the strain producing Pyrroxamycin.

    Ioxaglate sodium

    P-286 sodium

    		 Biochemical Assay Reagents Cardiovascular Disease Cancer
    Ioxaglate sodium (P-286 sodium) is an ionic, dimeric diagnostic contrast agent whose activity is mainly reflected in its ability to provide sufficient X-ray absorption to enhance visualization of blood vessels and other structures during imaging. Ioxaglate sodium is used to study the anatomical structure and functional status of cardiac vessels, especially in the diagnosis of coronary artery disease .

    Aucubigenin

    		Others Others
    Aucubigenin, the aglycone of the iridoid glycoside aucubin, has been characterized through X-ray diffraction analysis. Its crystal structure reveals monoclinic symmetry with specific conformations adopted by its cyclopentane and pyran rings. The study also determined the absolute configurations of both aucubin and aucubigenin. Significant O–H?O hydrogen bonding interactions were observed in the crystal lattices of both compounds, highlighting their structural stability and potential for intermolecular interactions .
