The COVID-19 pandemic threatens to overwhelm healthcare systems around the world. The only current FDA-approved treatment, which directly targets the virus, is the ProTide prodrug remdesivir. In its activated form, remdesivir prevents viral replication by inhibiting the essential RNA-dependent RNA polymerase. Like other ProTide prodrugs, remdesivir contains a chiral phosphorus center. The initial selection of the (SP)-diastereomer for remdesivir was reportedly due to the difficulty in producing the pure (RP)-diastereomer of the required precursor. However, the two currently known enzymes responsible for the initial activation step of remdesivir are each stereoselective and show differential tissue distribution. Given the ability of the COVID-19 virus to infect a wide array of tissue types, inclusion of the (RP)-diastereomer may be of clinical significance. To help overcome the challenge of obtaining the pure (RP)-diastereomer of remdesivir, we have developed a novel chemoenzymatic strategy that utilizes a stereoselective variant of the phosphotriesterase from Pseudomonas diminuta to enable the facile isolation of the pure (RP)-diastereomer of the chiral precursor for the chemical synthesis of the (RP)-diastereomer of remdesivir.
METHODS AND REAGENTS FOR CROSS-LINKING CELLULAR DNA AND RNA VIA STRAIN-PROMOTED DOUBLE-CLICK REACTIONS

Sheet 1/19, (2020/01/24)
The present invention relates to new reagents and methods for modifying nucleic acids where an azide-containing nucleoside or nucleotide derivative is applied to living cells followed by a nitrogenous derivative of dibenzo-1,5-cyclooctadiyne (CODY). The azide- containing derivative is metabolically incorporated into cellular DNA and/or RNA, and the CODY derivative undergoes a strain-promoted double-click reaction to give nucleic acid – nucleic acid cross links, and/or optionally, in the presence of an exogenously added azide (X- N3); to give nucleic acid – "X" cross links.
