This manuscript deals with the synthesis and computational and experimental evaluation of the antimicrobial activity of twenty-nine 4-(indol-3-yl)thiazole-2-amines and 4-ιndol-3-yl)thiazole acylamines. An evaluation of antibacterial activity against Gram (+) and Gram (?) bacteria revealed that the MIC of indole derivatives is in the range of 0.06–1.88 mg/mL, while among fourteen methylindole derivatives, only six were active, with an MIC in the range of of 0.47–1.88 mg/mL. S. aureus appeared to be the most resistant strain, while S. Typhimurium was the most sensitive. Compound 5x was the most promising, with an MIC in the range of 0.06–0.12 mg/mL, followed by 5d and 5m. An evaluation of these three compounds against resistant strains, namely MRSA P. aeruginosa and E. coli, revealed that they were more potent against MRSA than ampicillin. Furthermore, compounds 5m and 5x were superior inhibitors of biofilm formation, compared to ampicillin and streptomycin, in terms Compounds 5d, 5m, and 5x interact with streptomycin in additive manner. The antifungal activity of some compounds exceeded or was equipotent to those of the reference antifungal agents bifonazole and ketoconazole. The most potent antifungal agent was found to be compound 5g. Drug likeness scores of compounds was in a range of ?0.63 to 0.29, which is moderate to good. According to docking studies, E. coli MurB inhibition is probably responsible for the antibacterial activity of compounds, whereas CYP51 inhibition was implicated in antifungal activity. Compounds appeared to be non-toxic, according to the cytotoxicity assessment in MRC-5 cells.

A general and direct C3 functionalization of free (N-H) indoles with readily available electrophiles such as acid chlorides, chloroformates, thionyl chloride, and methylsulfonyl chloride via a common N-indolyl triethylborate intermediate is reported. The reaction proceeds smoothly under mild conditions in up to 93% yield. Indoles with substituents at the C2, C4, C5, C6, and C7 positions are well tolerated. The easy accessibility of a variety of important 3-acylindoles, indole-3-carboxylic esters, indole-3-sulfinic acids, and 3-(methylsulfonyl)indoles demonstrates the high degree of compatibility and practicability of this method.

Structure-activity relationships within the indole-3-glyoxylamide series of antiprion agents have been explored further, resulting in discovery of several new compounds demonstrating excellent activity in a cell line model of prion disease (EC50 10 nM). After examining a range of substituents at the para-position of the N-phenylglyoxylamide moiety, five-membered heterocycles containing at least two heteroatoms were found to be optimal for the antiprion effect. A number of modifications were made to probe the importance of the glyoxylamide substructure, although none were well tolerated. The most potent compounds did, however, prove largely stable towards microsomal metabolism, and the most active library member cured scrapie-infected cells indefinitely on administration of a single treatment. The present results thereby confirm the indole-3-glyoxylamides as a promising lead series for continuing in vitro and in vivo evaluation against prion disease.Making mad cows a myth! The indole-3-glyoxylamide series of antiprion agents has been further optimised, and characteristics contributing to their activity have been identified by computational studies. Varying the glyoxylamide motif or introducing substitution at N-1 gave analogues with lower efficacy.

As an extension of our studies, novel indole derivatives were rationally designed and synthesized as ligands targeted to GluN2B/NMDA receptors. The 2-(4-benzylpiperidin-1-yl)-1-(6-hydroxy-1H-indol-3-yl)ethanone (4i) and 1-(4-benzylpiperidin-1-yl)-2-(6-hydroxy-1H-indol-3-yl)ethane-1,2-dione (6i) showed high binding affinity in [3H]ifenprodil displacement assay. By computational studies, we suggested the hypothetical interactions playing a significant role during the binding process. However, in functional and in vivo studies the most potent compound 4i did not show any activity whereas it displayed relevant affinity toward the σ2 receptor.

A combined ligand-based and structure-based approach has previously allowed us to identify NR2B/NMDA receptor antagonists containing indole scaffold. In order to further explore the main structure activity relationships of this class of derivatives we herein report the design, synthesis and biological evaluation of new analogues. Some derivatives demonstrated to produce significant anticonvulsant properties and NMDA antagonism. The most active of them (3d) showed NR2B binding affinity equipotent to that of ifenprodil. These results were also corroborated by computational studies.
