Abstract
Nerol, a linear monoterpenoid, is naturally found in essential oils of various plants and is widely used in the fragrance, food, and cosmetic industries. Nerol synthase, essential for nerol biosynthesis, has previously been identified only in plants that use NPP as the precursor. In this study, a novel fungal nerol synthase, named PgfB, was cloned and characterized from Penicillium griseofulvum. In vitro enzymatic assays showed that PgfB could directly convert the substrate GPP into nerol. Furthermore, the successful expression of PgfB and its homologous protein in Saccharomyces cerevisiae resulted in the heterologous production of nerol. Finally, crucial amino acid residues for PgfB's catalytic activity were identified through site-directed mutagenesis. This research broadens our understanding of fungal monoterpene synthases and presents precious gene resources for the industrial production of nerol.

(-)-Carvone Modulates Intracellular Calcium Signaling with Antiarrhythmic Action in Rat Hearts. Arq Bras Cardiol 2022; 119:294-304.

Abstract
Fundamento: A (-)-carvona é um monoterpeno encontrado em óleos essenciais com atividade antioxidante e anti-inflamátoria. Objetivos: O objetivo deste estudo foi analisar a propriedade antiarrítmica da (-)-carvona no coração de rato e seus efeitos sobre a sinalização de Ca+2 intracelular. Métodos: Os efeitos da (-)-carvona foram avaliados sobre a contratilidade atrial (0,01 – 4 mM) e ventricular (0,5 mM), e no eletrocardiograma (0,5mM). A fração de encurtamento, a corrente de cálcio do tipo L (ICa,L) e a sinalização de Ca+2 foram medidas no cardiomiócito isolado (0,5 mM). O efeito antiarrítmico foi avaliado no modelo de arritmia induzida por sobrecarga de cálcio (0,5 mM) (n = 5). Um p < 0,05 foi adotado como nível de significância estatística. Resultados: No átrio, a (-)-carvona causou inotropismo negativo de maneira concentração-dependente (EC50 0,44 ± 0,11 mM) e diminuiu o inotropismo positivo induzido pelo CaCl2 (0,1 – 8,0 mM) e BAY K8644 (5 - 500 nM), um agonista de canal de cálcio do tipo L. Em coração isolado, a (-)-carvona (0,5mM) reduziu a contratilidade ventricular em 73% e a frequência cardíaca (em 46%), aumentou o Pri (30,7%, tempo desde o início da onda P até a onda R) e o QTc (9,2%, uma medida de despolarização e repolarização dos ventrículos), sem mudar a duração do complexo QRS. A (-)-carvona diminuiu a fração de encurtamento (61%), a (ICa,L) (79%) e o transiente intracelular de Ca+2 (38%). Além disso, a (-)-carvona apresentou ação antiarrítmica, identificada pela redução do escore de arritmia (85%) e ocorrência de fibrilação ventricular. Conclusão: A (-)-carvona reduz a entrada de Ca+2 através de canais de Ca+2 do tipo L e, assim, diminui a contratilidade cardíaca e o Ca+2 intracelular e apresenta promissora atividade antiarrítmica no coração de ratos.

Monoterpenes and their derivatives as agents for cardiovascular disease management: A systematic review and meta-analysis. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 88:153451. [PMID: 33483251 DOI: 10.1016/j.phymed.2020.153451] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 11/16/2020] [Accepted: 12/22/2020] [Indexed: 06/12/2023]
Abstract
BACKGROUND Monoterpenes are one of the most studied plant's secondary metabolites, they are found abundantly in essential oils of aromatic plants. They also have a great range of pharmacological properties, such as antihypertensive, bradycardic, antiarrhythmic and hypotensive. In the face of the burden caused by cardiovascular disease (CVDs) worldwide, studies using monoterpenes to assess their cardiovascular effects have increased over the years. PURPOSE This systematic review aimed to summarize the use of monoterpenes in animal models of any CVDs. METHODS PubMed, SCOPUS, LILACS and Web of Science databases were used to search for articles that used monoterpenes, in any type of administration, to treat or prevent CVDs in animal models. The PRISMA guidelines were followed. Two independent researchers extracted main characteristics of studies, methods and outcomes. Data obtained were analyzed qualitatively and quantitatively. RESULTS At the ending of the search process, 33 articles were selected for the systematic review. Of these, 17 articles were included in the meta-analysis. A total of 16 different monoterpenes were found for the treatment of hypertension, myocardial infarction, pulmonary hypertension, cardiac hypertrophy and arrhythmia. The main actions include hypotension, bradycardia, vasodilatation, antiarrhythmic, and antioxidant and antiapoptotic properties. From our data, it can be suggested that monoterpenes may be a significant source for new drug development. However, there is still a need to apply these knowledge into clinical research and a long path to pursue before putting them in the market. CONCLUSION The variability of cardiovascular effects demonstrated by the monoterpenes highlighted them as a promising candidates for treatment or prevention of CVDs. Nevertheless, studies that investigate their biological sites of action needs to be further encouraged.
