Paragraph 0019-0033, (2021/01/24)
The invention discloses a preparation method of N, N-bis(trimethylsilyl)allylamine, which comprises the following steps: 1. dropwisely adding an organic alkali solution into allyl bromide to carry outcondensation reaction, carrying out rotary evaporation to remove the organic solvent after the reaction is completed, and filtering to remove the generated metal salt, thereby obtaining a filtrate; and 2, adding deionized water into the filtrate, carrying out low-temperature water washing to remove metal salt and other water-soluble impurities, carrying out standing and liquid separation, separating out an organic phase, rectifying the organic phase, and collecting the N, N-bis(trimethylsilyl)allylamine finished product. The method has the advantages that 1, the reaction safety coefficient isgreatly improved, and the corrosion to equipment is effectively reduced; and 2, by-products or impurities generated in the preparation process are effectively removed, so that the purity and yield ofthe product are effectively improved.

In search of myosin II inhibitors with superior research tool properties, a chemical optimization campaign of the blebbistatin scaffold was conducted in this paper. (S)-Blebbistatin is the best known small-molecule inhibitor of myosin II ATPase activity. Unfortunately, as a research tool this compound has several deficiencies: it is photolabile and (photo)toxic, has low water solubility, and its (fluorescent) precipitates interfere in (fluorescence) readouts. In view of obtaining tool compounds with improved properties, both enantiomers of a series of D-ring modified polar analogs were prepared. We identified (S)-3′-hydroxyblebbistatin (S)-2 and (S)-3′-aminoblebbistatin (S)-3 as two myosin II inhibitors with a 30-fold higher water solubility than (S)-blebbistatin. These molecules furthermore do not cause interference in (fluorescence) readouts. (S)-2 and (S)-3 thus are superior alternatives to (S)-blebbistatin as research tools to study myosin II.
