BACKGROUND Fusarium solani f. sp. piperis is a phytopathogen that causes one of the most destructive diseases in black pepper crops, resulting in significant economic and crop production losses. Consequently, the control of this fungal disease is a matter of current and relevant interest for agriculture. OBJECTIVE The objective was to synthesize eugenol derivatives with antifungal activity. METHODS In this study, using bimolecular nucleophilic substitution and click chemistry approaches, four new and three known eugenol derivatives were obtained. The eugenol derivatives were characterized, and their antifungal and cytotoxic effects were evaluated. RESULTS Eugenol derivative 4 (2-(4-allyl-2-methoxyphenoxy)-3-chloronaphthalene-1,4-dione) was the most active against F. solani f. sp. piperis and showed acceptable cytotoxicity. Compound 4 was two-fold more effective than tebuconazole in an antifungal assay and presented similar cytotoxicity in macrophages. Necrostatin-1 concentration The in silico study of β-glucosidase suggests a potential interaction of 4 with amino acid residues by a cation-π interaction with residue Arg177 followed by a hydrogen bond with Glu596, indicating an important role in the interactions with 4, justifying the antifungal action of this compound. In addition, the cytotoxicity after metabolism was evaluated as a mimic assay with the S9 fraction in HepG2 cells. Compound 4 demonstrated maintenance of cytotoxicity, showing IC50 values of 11.18 ± 0.5 and 9.04 ± 0.2 μg mL-1 without and with the S9 fraction, respectively. In contrast, eugenol (257.9 ± 0.4 and 133.5 ± 0.8 μg mL-1 ), tebuconazole (34.94 ± 0.2 and 26.76 ± 0.17 μg mL-1 ) and especially carbendazim (251.0 ± 0.30 and 34.7 ± 0.10 μg mL-1 ) showed greater cytotoxicity after hepatic biotransformation. CONCLUSION The results suggest that 4 is a potential candidate for use in the design of new and effective compounds that could control this pathogen.

Globally, tuberculosis poses the most substantial burden of mortality. Further, partially treated tuberculosis patient is worse than an untreated; they may lead to stands out as a critical obstacle to global tuberculosis control. The emergence of multi-drug resistant (MDR) and extremely drug-resistant (XDR) strains, and co-infection of HIV further worsen the situation. The present review article, discusses validated targets of the bacterial enzyme thymidine monophosphate kinase (TMPK). TMPKMTB enzyme belongs to the nucleoside monophosphate kinases (NMPKs) family. It is involved in phosphorylation of TMP to TDP, and TDP is phosphorylated to TTP. This review highlights structure elucidation of TMP enzymes and their inhibitors study on TMP scaffold, and it also discusses different techniques; including molecular docking, virtual screening, 3D-Pharmacophore, QSAR for finding antitubercular agents.

Endothelial dysfunction, characterized by a decline in nitric oxide production and/or bioavailability, increased oxidative stress, decreased prostacyclin levels, and a reduction of endothelium-derived hyperpolarizing factor is considered an important prognostic indicator of various CVD. Changes in cyclic nucleotides production and/ or signalling, such as guanosine 3', 5'-monophosphate (cGMP) and adenosine 3', 5'-monophosphate (cAMP), also accompany many vascular disorders that course with altered endothelial function. Phosphodiesterases (PDE) are metallophosphohydrolases that catalyse cAMP and cGMP hydrolysis, thereby terminating the cyclic nucleotide-dependent signalling. The development of drugs that selectively block the activity of specific PDE families remains of great interest to the research, clinical and pharmaceutical industries. In the present review, we will discuss the effects of PDE inhibitors in CVD related to altered endothelial function, such as atherosclerosis, diabetes mellitus, arterial hypertension, stroke, aging and cirrhosis. Multiple evidences suggest that PDEs inhibition represents an attractive medical approach for the treatment of endothelial dysfunction-related diseases. Selective PDE inhibitors, especially PDE3 and PDE5 inhibitors are proposed to increase vascular NO levels by increasing antioxidant status or endothelial nitric oxide synthase expression and activation, and to improve the morphological architecture of the endothelial surface. Thereby, selective PDE inhibitors can improve the endothelial function in various CVD, increasing the evidence that these drugs are potential treatment strategies for vascular dysfunction and reinforcing their potential role as adjuvant in the pharmacotherapy of CVD.

One of the solutions can be found in the oceans due to algae. Microalgae are aquatic photosynthetic organisms largely used due to their variety of bioactive compounds. The consumption of microalgae has been carried out for centuries and is recommended by organizations such as OMS and FAO due to its nutritional value and its properties. Based on the existing literature, there is substantial evidence of the nutritional quality of the algae as well as their functional elements. However, much quantification is still necessary as well as studying possible adverse effects. The present review describes the compounds of alimentary interest present in these algae as well as different extraction techniques assisted by different energetic mechanisms (such as heat, supercritical-fluid, microwave, ultrasound, enzymes, electric field, high hydrostatic pressure, among others). The most challenging and crucial issues are reducing microalgae growth cost and optimizing extraction techniques.
