Disclosed are a steroidal compound as shown in formula (I) and a drug composition containing the same, or a crystal form, a pharmaceutically acceptable salt, a hydrate or solvate, a stereoisomer, a prodrug, a metabolite or an isotopic variant thereof. The compound can be used as a CYP17 ...
in the presence of L-Phe. The fluorescence-activated cell sorting (FACS) was applied to preform high-throughput screening (HTS) of the L-Phe producing strains with the help of the L-Phe biosensor[167]. In another study, avanillinself-inducible promoterADH7was used for the control of an ...
It has the crystal structure of space group I41/amd with lattice parameters of a = b = 11.2743(1) Å and c = 15.9170(2) Å, characterized by the synchrotron powder X-ray diffraction (SR-PXRD). High-resolution transmission electron microscopy (HR-TEM) is used to ...
This invention relates to polymers suitable as the base resin in chemically amplified positive resist compositions used for micropatterning in a process for the fabrication of semiconductor devices. It also relates to polymerizable silicon-containing compounds for the polymers and a method of preparing th...
When a hydrogen halide adds to the carbon-carbontriple bondof an alkyne, addition of the first molecule is faster than the second, and a vinylic halide can be isolated. Chloroprene, themonomerused in the formation of theelastomerneoprene, is prepared from vinylacetylene by this reaction. ...
Magnetic field-assisted polishing is widely used in the machining of optical compo- nents and semiconductors with high precision and high surface quality [11,12], and it has no subsurface damage and good controllability in the machining process. Compared with other polishing methods, magnetic field...
In a previous study, we found that the marine-derived compound 11-dehydrosinulariolide (11-de) upregulates the Akt/PI3K pathway to protect cells against 6-hydroxydopamine (6-OHDA)-mediated damage. In the present study, SH-SY5Y, zebrafish and rats were used to examine the therapeutic effect ...
The slow evaporation method was used to form single crystals of the named compound from methanolic solution. The compound was characterized by X-ray crystallographic analysis and spectroscopic methods (NMR, IR, mass spectrometry, and UV-vis). The sulfonamide N-H NMR signal at 8.07–8.09 ppm and...
Our nature-aided drug discovery research takes place as a response to this situation. As part of our ongoing study on the phytochemical characterization and biological investigation of plants used in western central Asia traditional medicine [5], we addressed our attention to plants belonging to ...
