Out of nine different 7-deaza-adenosine diarylethenes, we identified a high-performance photoswitch, suitable for the synthesis of photochromic DNA. By using solid phase synthesis, a photoresponsive T7 promotor was generated which allowed reversibly modulating the rate of enzymatic RNA synthesisin vitro.

Preparation method of baricitinib
-
Paragraph 0033; 0034; 0035, (2017/09/29)
The invention discloses a preparation method of baricitinib. The method comprises the following steps: performing a substitution reaction on 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (II) serving as a raw material and benzene sulfonyl chloride in the presence of an alkali to obtain an intermediate III; then, performing a Suzuki coupling reaction on the intermediate III and 4-pyrazole-4-boronic acid pinacol ester in the presence of a palladium catalytic system and an alkali to obtain an intermediate V; then performing a Michael addition reaction on the intermediate V and 3-(cyanomethylene)azetidine-1-tert-butyl formate in the presence of a catalyst to obtain an intermediate VII; then removing Boc protection from the intermediate VII under the action of hydrochloric acid to obtain an intermediate VIII; then performing a sulfoamidate reaction on the intermediate VIII and ethyl sulfonyl chloride in an organic solvent in the presence of an alkali to obtain an intermediate IX; lastly, removing benzenesulfonyl protection from the intermediate IX under the action of tetramethylammonium fluoride or tetrabutylammonium fluoride or a trihydrate of the tetramethylammonium fluoride or the tetrabutylammonium fluoride to obtain baricitinib (I). Compared with the prior art, the method has the advantages of adoption of readily-available raw materials, low cost, high product yield and easiness for industrial production.
The role of alkyl substituents in deazaadenine-based diarylethene photoswitches
Sarter, Christopher,Heimes, Michael,J?schke, Andres
supporting information, p. 1103 - 1110 (2016/07/06)
Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement. Here we probe this claim by the synthesis and characterization of four pairs of deazaadenine-based diarylethene photoswitches with either one or two methyl groups at these positions. Depending on the substitution pattern, diarylethenes with one alkyl group can exhibit significant photochromism, but they generally show poor stability towards extended UV irradiation, low thermal stability, and decreased fatigue resistance. The results obtained provide an important direction for the design of new efficient DNA photoswitches for the application in bionanotechnology and synthetic biology.
