Indole-Containing Phytoalexin-Based Bioisosteres as Antifungals: In Vitro and In Silico Evaluation against Fusarium oxysporum

There is a continuous search for more reliable and effective alternatives to control phytopathogens through different strategies. In this context, indole-containing phytoalexins are stimuli-induced compounds implicated in plant defense against plant pathogens. However, phytoalexins’ efficacy have been limited by fungal detoxifying mechanisms, thus, the research on bioisosteres-based analogs can be a friendly alternative regarding the control of Fusarium phytopathogens, but there are currently few studies on it. Thus, as part of our research on antifungal agents, a set of 21 synthetic indole-containing phytoalexin analogs were evaluated as inhibitors against the phyopathogen Fusarium oxysporum. Results indicated that analogs of the N,N-dialkylthiourea, N,S-dialkyldithiocarbamate and substituted-1,3-thiazolidin-5-one groups exhibited the best docking scores and interaction profiles within the active site of Fusarium spp. enzymes. Vina scores exhibited correlation with experimental mycelial growth inhibition using supervised statistics, and this antifungal dataset correlated with molecular interaction fields after CoMFA. Compound 24 (tert-butyl (((3-oxo-1,3-diphenylpropyl)thio)carbonothioyl)-L-tryptophanate), a very active analog against F. oxysporum, exhibited the best interaction with lanosterol 14 alpha-demethylase according to molecular docking, molecular dynamics and molecular mechanic/poisson-boltzmann surface area (MM/PBSA) binding energy performance. After data analyses, information on mycelial growth inhibitors, structural requirements and putative enzyme targets may be used in further antifungal development based on phytoalexin analogs for controlling phytopathogens.

Corrosion Inhibition of Stainless Steel Type 316 L in 1.0 M HCl Solution Using 1,3-Thiazolidin-5-one Derivatives

Ten compounds of 1,3-thiazolidin-5-one derivatives has been evaluated as an inhibitor for corrosion of stainless steel type 316L (316SS) in 1.0 M HCl solution by means of weight loss and electrochemical impedance spectroscopy techniques. The surface examination and morphological studies were studied using scanning electron microscope (SEM) and energy dispersive X-ray (EDX). It has been found that the percentage inhibition efficiency increases with increasing the concentration of inhibitors and with decreasing temperature. These compounds acted as mixed type inhibitors. The inhibition process was explained due to the adsorption of these compounds at the 316 SS surface. The adsorption obeys Temkin’s isotherm. The effect of substituted group and substituted position on the inhibition efficiency were explained. SEM and EDS confirmed that the rate of 316SS corrosion in1.0 M HCl solution is reduced due to the formation of the protective film on its surface.

One-pot four-component synthesis of thiazolidin-2-imines using Cu-I/Zn-II dual catalysis: A new class of acetylcholinesterase inhibitors

An efficient one-pot four-component strategy involving aldehydes, amines, alkynes and isothiocyanates has been developed to access a novel series of thiazolidine-2-imines (5a-x). This process operates under the action of a cooperative catalysis composed of Cu(I) and Zn(II) delivering the desired five-membered heterocyclic compounds in good to excellent yields. Notably, this transformation avoids the use of pre-formed imines or propargylamines and proceeds via an intramolecular 5-exo-dig hydrothiolation reaction of the in situ formed propargyl thiourea. Furthermore, the biological application of these motifs was demonstrated in terms of their strong acetylcholinesterase (AChE) inhibitory activity where compound 5s was identified as the lead AChE inhibitor with an IC50, value of 0.0023 +/- 0.0002 mu M, 88-folds stronger inhibition than standard drug (neostigmine methyl sulphate; IC50, = 0.203 +/- 0.004 mu M). Molecular docking analysis reinforced the in vitro biological activity results revealing the formation of several useful interactions of the potent lead with amino acid residues in the active site of the enzyme.

Utility of chloroacetonitrile in construction of some hitherto novel pyrazole and thiazole derivatives

2-(-Piperidin-1-yl) acetamide (2) was easily prepared by reacting chloroacetonitrile with piperidine. Furthermore, (2) was allowed to react with different aromatic aldehydes to afford novel arylidene derivatives (3a,b). Unexpectedly, 2-oxo-4-hydroxy-thiazole (5) was obtained instead of 2-(piperidin-1-yl-methylene) thiazolidin-4-one (4) when (2) was treated with mercaptoacetic acid under fusion conditions. Subsequent treatment of (5) with aromatic aldehydes and either malononitrile or cyanoacetamide (1:1:1 molar ratios) produced the hitherto unknown pyrano[2,3-d] thiazole derivatives (6a,b) and (7). Novel pyrazole derivatives (8a, b) and (9) were synthesized upon cyclocondensation of (2) with aromatic aldehydes and hydrazine hydrate. Unfortunately, attempts to prepare novel isoxazole derivatives by utilizing hydroxylamine instead of hydrazine hydrate following the previous procedure were failed. Surprisingly, the uncyclized products (10a,b) were obtained rather than 3-hydroxy-4-piperidinyl-isoxazole (11a,b). Upon refluxing thiosemicarbazide with (2) and aromatic aldehydes under the same conditions, pyrazolinone carbothioamides (12), (13) and (14a-c) were obtained.

Intracellular distribution of new tacrine analogues as a potential cause of their cytotoxicity against human neuroblastoma cells SH-SY5Y

Four new glyco-conjugated tacrine derivatives, 4-(2,3,4,6-tetra-O-acetyl–D-glucopyranosyl)-1-(1,2,3,4-tetrahydroacridin-9-yl)thiosemicarbazide (1), 4-(2,3,4,6-tetra-O-acetyl–D-mannopyranosyl)-1-(1,2,3,4-tetrahydroacridin-9-yl)thiosemicarbazide (2), 2-(1,2,3,4-tetrahydroacridin-9-yl)hydrazono-3-(2,3,4,6-tetra-O-acetyl–D-galactopyranosyl)-1,3-thiazolidin-4-one (3) and [2-(1,2,3,4-tetrahydro-acridin-9-yl)hydrazono-3-(2,3,4,6-tetra-O-acetyl–D-glucopyranosyl)-4-oxothiazolidin-5-yliden]acetate (4) were synthesized and their characteristics were investigated. All of the novel derivatives were found to inhibit acetylcholinesterase obtained from Electrophorus electricus at a magnitude of one order less than that of the control tacrine. Derivatives 1-3 were found to be nontoxic towards human neuroblastoma SH-SY5Y cells, while compound 4 was markedly cytotoxic against these cells (IC50 value 2 mu M, 72h). These differences in cytotoxicity were examined further by investigating the uptake and intracellular localization of the tacrine derivatives. Non-cytotoxic derivatives 1-3 were found to localize outside of the nuclei, showing a marked preference for the lysosomes and the mitochondria; in contrast, the cytotoxic derivative 4 was localized in the nuclei of the neuroblastoma cells. Interaction studies revealed that derivative 4 displays a high affinity towards DNA, and also provided evidence of the compound’s ability to inhibit Topo I.
