In Vitro and In Silico Evaluation of the Leishmanicidal and Trypanocidal Activities of Lignan Methylpiperitol Isolated from Persea Fulva. Chem Biodivers 2024; 21:e202400678.

Abstract
Neglected Tropical Diseases are a significant concern as they encompass various infections caused by pathogens prevalent in tropical regions. The limited and often highly toxic treatment options for these diseases necessitate the exploration of new therapeutic candidates. In the present study, the lignan methylpiperitol was isolated after several chromatographic steps from Persea fulva L. E. Koop (Lauraceae) and its leishmanicidal and trypanocidal activities were evaluated using in vitro and in silico approaches. The chemical structure of methylpiperitol was defined by NMR and MS spectral data analysis. The antiprotozoal activity of methylpiperitol was determined in vitro and indicated potency against trypomastigote forms of Trypanosoma cruzi (EC50 of 4.5±1.1 mM) and amastigote forms of Leishmania infantum (EC50 of 4.1±0.5 mM), with no mammalian cytotoxicity against NCTC cells (CC50>200 mM). Molecular docking studies were conducted using six T. cruzi and four Leishmania. The results indicate that for the molecular target hypoxanthine phosphoribosyl transferase in T. cruzi and piteridine reductase 1 of L. infatum, the methylpiperitol obtained better results than the crystallographic ligand. Therefore, the lignan methylpiperitol, isolated from P. fulva holds potential for the development of new prototypes for the treatment of Neglected Tropical Diseases, especially leishmaniasis.

Abstract
A two-step enantioselective gram scale synthesis of the Persea derived γ-lactones (+)-majoranolide and (+)-majoranolide B has been achieved. The sequence uses the amine promoted crossed condensation of the biorenewable synthon Cyrene with aliphatic aldehydes followed by a Baeyer-Villiger oxidation. Comparison of optical rotation data with the natural products established the absolute configuration of the natural product series, and this work represents the first synthesis of these alkylidene natural products.

Phytochemistry and Pharmacology of Medicinal Plants Used by the Tenggerese Society in Java Island of Indonesia. Molecules 2022; 27:molecules27217532. [DOI: 10.3390/molecules27217532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 10/30/2022] [Accepted: 11/01/2022] [Indexed: 11/06/2022] Open
Abstract
The archipelagic country of Indonesia is inhabited by 300 ethnic groups, including the indigenous people of Tengger. Based on the reported list of medicinal plants used by the Tengger community, we have reviewed each of them for their phytochemical constituents and pharmacological activities. Out of a total of 41 medicinal plants used by the Tengerrese people, 33 species were studied for their phytochemical and pharmacological properties. More than 554 phytochemicals with diverse molecular structures belonging to different chemical classes including flavonoids, terpenoids, saponins and volatiles were identified from these studied 34 medicinal plants. Many of these medicinal plants and their compounds have been tested for various pharmacological activities including anti-inflammatory, antimicrobial, wound healing, headache, antimalarial and hypertension. Five popularly used medicinal plants by the healers were Garcinia mangostana, Apium graveolens, Cayratia clematidea, Drymocallis arguta and Elaeocarpus longifolius. Only A. graviolens were previously studied, with the outcomes supporting the pharmacological claims to treat hypertension. Few unexplored medicinal plants are Physalis lagascae, Piper amplum, Rosa tomentosa and Tagetes tenuifolia, and they present great potential for biodiscovery and drug lead identification.
