    The COVID -19 pandemic is a stark reminder that a barren global antiviral pipeline has grave humanitarian consequences. Future pandemics could be prevented by accessible, easily deployable broad-spectrum oral antivirals and open knowledge bases that derisk and accelerate novel antiviral discovery and development. Here, we report the results of the COVID

    Hence, 15 Homovanilic acid is not recognized by either p-BAPCV ⊂ bCA or p-BAPCV ⊂ hCAII suggesting that the catechol moiety plays a critical role for the recognition of the analyte. p-BAPCV ⊂ bCA II and p-BAPCV ⊂ hCAII follows the same trend in recognition of analytes suggesting that the active sites of both proteins are similar and pursue similar recognition patterns (see Figure 4). 9 dopamine is preferentially recognized over 16 DOPAC suggesting that the functional group at the tale of the neurotransmitter interacts with the second coordination of CA. A positive charge plays a key role in the recognition process (9 dopamine) over a negative charge (16 DOPAC). 3.1 Detection of analytes discussion In order to understand the mechanism of selection discriminating the recognition between 9 dopamine and 16 DOPAC we sought to manually dock 9 dopamine inside p-BA ⊂ hCAII. Upon manual bond rotation we found that F-131 was close lying to the tail of 9 dopamine (see Figure 3). We then realized that the close proximity of an aromatic ring to an amine may lead to an NH/π interaction that could stabilize the interaction between 9

    However, the less nucleophilic ammonia in methanol not only deprotected the primary amine but also resulted in spontaneous cyclization to give (+)- dehydrodeoxybrevianamide E (9 ) in 49% yield over the three steps from methyl ester 17.28 Thus, the total synthesis of (+)-dehydrodeoxybrevianamide E (9 ) has been achieved in a longest linear sequence of 5 steps, in 35% overall yield, and requires just 2 chromatographic purifications (cf. previous synthesis: 12 steps, 8% overall yield).12g-h Scheme 4.
