Red: the arrows show the notation for the three distinct 5-OHs. Yield after each step is given as percentage in brackets. HClO4-SiO2 perchloric acid on silica gel, BSTFA N,O-bis(trimethylsilyl)trifluoroacetamide, DMT 4,4′-dimethoxytrityl, TBAF tetra-n-butylammonium fluoride, DCI 4,5-...
Hard disk drives are described and advertised by manufacturers in terms of decimal (base 10) capacity. Microsoft Windows and other programs, such as FDISK, use the binary (base 2) numbering system. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, and one gigabyte (GB...
(mAl) notation (n = 0–4, m = 0∼n) was used, in which the superscript n means the number of neighboring tetrahedral SiO4 linked to a given SiO4 tetrahedron and m indicates the number of aluminum atoms, which have a chemical bond through the oxygen bridge to the silicon of ...
This is in part because, unlike our extensive knowledge of the structure and function of the proteins in the virion (1, 2), there is no information on the lipid composition of the SARS-CoV2 envelope—indeed, viral lipid envelopes overall are surprisingly unstudied, and their detailed lipid ...
a The nanoconfined cascade in downstream notation. Enzymes E1 and E2 are, respectively, FNR and a NAD(P)(H) dehydrogenase and they represent the transducer-engine pair at which the rate of reaction flow along the cascade is recorded directly as current. Here the rest of the cascade is downs...

As used herein, the notation “*” shall denote the presence of a stereogenic center. Where the compounds according to this invention have at least one chiral center, they may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as...
n is an integer of 0 to 4. As used herein, the notation ormeans a bond linked to another substituent group. As used herein, the term “substituted or unsubstituted” means being unsubstituted or substituted with one or more substituents selected from the group consisting of deuterium; a hal...
A medicinal preparation is desired which has no harmful side effects such as hypersensitive reaction, heightens the water solubility of a sparingly water-soluble anticancer agent, maintains a high drug concentration in the blood, accumulates a drug in a tumor tissue at a high concentration, heightens...
As used herein, the new numbering scheme for the Periodic Table Groups is the new notation as set out CHEMICAL AND ENGINEERING NEWS, 63(5), 27 (1985). As used herein, a polymer may be used to refer to homopolymers, copolymers, interpolymers, terpolymers, etc. Likewise, a copolymer may...
