Non-covalent inhibitors of the main protease (Mpro) of SARS-CoV-2 having a pyridinone core were previously reported with IC50 values as low as 0.018 μM for inhibition of enzymatic activity and EC50 values as low as 0.8 μM for inhibition of viral replication in Vero E6 cells. The series has now been further advanced by consideration of placement of substituted five-membered-ring heterocycles in the S4 pocket of Mpro and N-methylation of a uracil ring. Free energy perturbation calculations provided guidance on the choice of the heterocycles, and protein crystallography confirmed the desired S4 placement. Here we report inhibitors with EC50 values as low as 0.080 μM, while remdesivir yields values of 0.5-2 μM in side-by-side testing with infectious SARS-CoV-2. A key factor in the improvement is enhanced cell permeability, as reflected in PAMPA measurements. Compounds 19 and 21 are particularly promising as potential therapies for COVID-19, featuring IC50 values of 0.044-0.061 μM, EC50 values of ca. 0.1 μM, good aqueous solubility, and no cytotoxicity.

Versatile Photochemical Reactivity of Diverse Substituted 2-, 4- and 5-(o-Vinylstyryl)oxazoles
?agud, Ivana,?indler-Kulyk, Marija,Vojnovi?-Jandri?, Dragana,Marini?, ?eljko
, p. 515 - 524 (2018/02/09)
To study the effects of the position of the hexatrienyl moiety on the oxazole ring, novel substituted cis/trans-2/4/5-(2-vinylstyryl)oxazoles have been synthesized. These novel compounds were prepared by Wittig reaction from the diphosphonium salt of α,α′-o-xylenedibromide, formaldehyde and the corresponding 2-methyl-4-, 4-methyl-2-, 2-pheny-5- and 4-methyl-5-oxazolecarbaldehyde, respectively. Aldehydes were synthesized by using several synthetic approaches. By applying intramolecular photocycloaddition, 2-methyl-4-(2-vinylstyryl)oxazole afforded, as major product, fused oxazoline-benzobicyclo[3.2.1]octene with small quantities of 4-(1,2-dihydronaphthalen-2-yl)-2-methyloxazole, as electrocyclization product. Upon irradiation of 4-methyl-5-(2-vinylstyryl)oxazole, endo- and exo-benzobicyclo[2.1.1]hexene products were formed by [2+2] cycloaddition; this was the first instance of the 1,4-closure to the bicyclo[2.1.1]hexene skeleton in the 2-, 4-, and 5-oxazole-stilbene derivatives studied so far. Derivatives 2-phenyl-5- and 4-methyl-2-(2-vinylstyryl)oxazole did not react and gave only high-weight molecular products but were crucial as a comparison in the overall mechanistic study. We have found that, depending on the position of the hexatrienyl moiety in the oxazole ring, as well as on the position of the methyl/phenyl substituents, these new vinylstyryl-2/4/5-oxazole derivatives show diverse photochemical behavior.

Synthesis of oxazolyl-substituted morpholinium salts
Boulos, John,Stujenske, Christina
, p. 443 - 445 (2007/10/03)
Morpholinium salts coupled to oxazolyl moieties have been synthesized via nucleophilic substitution of a series of oxazolyl chlorides with morpholine. The oxazole moieties were first synthesized and then coupled with morpholine. The corresponding hydrochloride and methyl iodide salts were obtained, purified, characterized and then tested for muscarinic receptor binding affinity. Biological test results from MDS Pharma Services revealed no significant muscarinic receptor affinity.
