[PMID: 35344136 DOI: 10.1007/s11030-022-10416-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 02/22/2022] [Indexed: 02/08/2023]
Abstract
In this work, we have synthesized various organic compounds possessing 1,3,4-oxadiazole as a core structure and the structure of the newly synthesized target compounds has been revealed using different analytical approaches such as FT-IR, LCMS, and NMR (proton and carbon), respectively. The in vitro carbonic anhydrase potentials of these synthesized 17 different analogues were investigated. The result suggests that compound 7g, a 3-pyridine substituted analogue with an IC50 of 0.1 µM, was found to have the most potent carbonic inhibitory activity (11-fold more active) than the positive control (acetazolamide) with an IC50 of 1.1 ± 0.1 µM. Besides, among the series 7(a-q) approved in the identification of four potent carbonic anhydrase inhibitors with the IC50 standards varies from 0.1 to 1.0 ± 0.1 µM. Additionally, the non-competitive behaviour for potent compound 7g was analysed using the Lineweaver-Burk plot from the kinetic study. Furthermore, the anticancer activity of all the synthesized compounds screened against B16F10 melanoma cells using the MTT assay method. Additionally, the molecular docking studies revealed that 7g inhibitor shows good binding energy as well as good binding interaction pattern along with enzyme.

Abstract
Herein, we have synthesized quinoline united various Schiff base derivatives (Q1-Q13) and systematically characterized them using diverse analytical practices such as 1H NMR, 13C NMR, FT-IR and LC-MS respectively. All of the target compounds that have been synthesized were tested for elastase inhibition, and the findings were compared to the standard drug oleanolic acid. Among the entire series, compound Q11 (IC50 = 0.897 ± 0.015 µM) exhibit most promising elastase inhibitory activity than oleanolic acid (Standard) having an IC50 value of 13.426 ± 0.015 µM. Also, the utmost effectivecompound Q11 was used for kinetic mechanism investigation based on in-vitro data, from which it has been concluded that compound Q11 inhibits elastase competitively. Furthermore, utilizing the MTT test approach, the most effective compounds were assessed for cytotoxicity on B16F10 melanoma cells. From the cytotoxicity experiment, the most potent compound did not display any hazardous response against B16F10 melanoma cells despite being treated at high concentrations. Additionally, the molecular docking study was settled to govern the binding interaction pattern among an enzyme and inhibitors.

Abstract
Urease is a kind of enzyme which could be found in various bacteria, fungi, plants, and algae, which can quickly catalyze the hydrolysis of urea into ammonia and carbon dioxide. With the ammonia concentration increasing, the activity of Helicobacter pylori has got an obvious enhancement and leads to mucosal damage in the stomach, gastroduodenal infection, peptic ulcers, and gastric cancer. The infectious diseases caused by Helicobacter pylori can be controlled to a certain extent by inhibiting urease activity with urease inhibitors. Hence, studies of urease inhibitors have attracted great attention all over the world and a variety of effective urease inhibitors have been synthesized in recent years. In this review, we will draw summaries for these inhibitors including urease inhibitory activity, inhibition kinetics, structure-activity relationship, and molecular docking. The collected information is expected to provide rational guidance and effective strategy to develop novel, potent, and safe urease inhibitors for better practical applications in the future.

Abstract
Urease is an attractive drug target for designing anti-infective agents against pathogens such as Helicobacter pylori, Proteus mirabilis, and Ureaplasma urealyticum. In the past century, hundreds of medicinal chemists focused their efforts on explorations of urease inhibitors. Despite the FDA's approval of acetohydroxamic acid as a urease inhibitor for the treatment of struvite nephrolithiasis and the widespread use of N-(n-butyl)thiophosphoric triamide as a soil urease inhibitor as nitrogen fertilizer synergists in agriculture, urease inhibitors with high potency and safety are urgently needed. Exploration of novel urease inhibitors has therefore become a hot research topic recently. Herein, inhibitors identified worldwide from 2016 to 2021 have been reviewed. They structurally belong to more than 20 classes of compounds such as urea/thioure analogues, hydroxamic acids, sulfonamides, metal complexes, and triazoles. Some inhibitors showed excellent potency with IC50 values lower than 10 nM, having 10000-fold higher potency than the positive control thiourea.

Abstract
Urease is a metalloenzyme that catalyzes the hydrolysis of urea into ammonia and carbon dioxide, which has a negative impact on human health and agriculture. In this study, the inactivation of jack bean urease by nitidine chloride (NC) was investigated to elucidate the inhibitory effect, kinetics, and underlying mechanism of action. The results showed that NC acted as a concentration- and time-dependent inhibitor with an IC50 value of 33.2 ± 4.8 μM and exhibited a similar inhibitory effect to acetohydroxamic acid (IC50 = 31.7 ± 5.8 μM). Further kinetic analysis demonstrated that NC was a slow-binding and non-competitive inhibitor for urease. Thiol-blocking reagents (dithiothreitol, glutathione, and l-cysteine) significantly retarded urease inactivation, while Ni2+ competitive inhibitors (boric acid and sodium fluoride) synergetically suppressed urease with NC, suggesting that the active site sulfhydryl groups were possibly obligatory for NC blocking urease. Molecular docking simulation further argued its inhibition mechanism. Additionally, NC-induced deactivation of urease was verified to be reversible since the inactivated enzyme could be reactivated by glutathione. Taking together, NC was a non-competitive inhibitor targeting the thiol group at the active site of urease with characteristics of concentration dependence, reversibility, and slow binding, serving as a promising novel urease suppressant.

Novel 1,3,4-oxadiazole compounds inhibit the tyrosinase and melanin level: Synthesis, in-vitro, and in-silico studies. Bioorg Med Chem 2021; 41:116222.

Abstract
In this research work, we have designed and synthesized some biologically useful of 1,3,4-Oxadiazoles. The structural interpretation of the synthesized compounds has been validated by using FT-IR, LC-MS, HRMS, 1H NMR and 13C NMR techniques. Moreover, the in-vitro mushroom tyrosinase inhibitory potential of the target compounds was assessed. The in-vitro study reveals that, all compounds demonstrate an excellent tyrosinase inhibitory activity. Especially, 2-(5-(2-methoxyphenyl)-1,3,4-oxadiazol-2-ylthio)-N-phenylacetamide (IC50 = 0.003 ± 0.00 µM) confirms much more significant potent inhibition activity compared with standard drug kojic acid (IC50 = 16.83 ± 1.16 µM). Subsequently, the most potent five oxadiazole compounds were screened for cytotoxicity study against B16F10 melanoma cells using an MTT assay method. The survival rate for the most potent compound was more pleasant than other compounds. Furthermore, the western blot results proved that the most potent compound considerably decreased the expression level of tyrosinase at 50 µM (P < 0.05). The molecular docking investigation exposed that the utmost potent compound displayed the significant interactions pattern within the active region of the tyrosinase enzyme and which might be responsible for the decent inhibitory activity towards the enzyme. A molecular dynamic simulation experiment was presented to recognize the residual backbone stability of protein structure.
