Abstract
Norditerpenes are considered to be a common and widely studied class of bioactive compounds in plants, exhibiting a wide array of complex and diverse structural types and originating from various sources. Based on the number of carbons, norditerpenes can be categorized into C19, C18, C17, and C16 compounds. Up to now, 557 norditerpenes and their derivatives have been found in studies published between 2010 and 2023, distributed in 51 families and 132 species, with the largest number in Lamiaceae, Euphorbiaceae, and Cephalotaxaceae. These norditerpenes display versatile biological activities, including anti-tumor, anti-inflammatory, antimicrobial, and antioxidant properties, as well as inhibitory effects against HIV and α-glucosidase, and can be considered as an important source of treatment for a variety of diseases that had a high commercial value. This review provides a comprehensive summary of the plant sources, chemical structures, and biological activities of norditerpenes derived from natural sources, serving as a valuable reference for further research development and application in this field.

Selective cytotoxicity of ent-kaurene diterpenoids isolated from Baccharis lateralis and Baccharis retusa (Asteraceae). Arch Pharm (Weinheim) 2022; 355:e2200083. [PMID: 35556256 DOI: 10.1002/ardp.202200083] [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: 02/16/2022] [Revised: 04/18/2022] [Accepted: 04/21/2022] [Indexed: 11/05/2022]
Abstract
This study presents the cytotoxic activity evaluation of the natural diterpenes ent-kaurenoic acid (1) and its 15β-hydroxy (2), 15β-senecioyloxy (3), and 15β-tiglinoyloxy (4) derivatives, isolated from Brazilian native plants, Baccharis retusa and B. lateralis (Asteraceae). Using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) colorimetric assay, it was observed that compound 1 displayed in vitro activity towards the aggressive MDA-MB-231 adenocarcinoma cell line and reduced toxicity against MCF-10A nontumorigenic epithelial cells, indicating expressive selectivity. On the contrary, compounds 2-4 exhibited reduced toxicity and selectivity in both tested cell lines. Based on the chemical structures of compounds 1-4, it is suggested that the presence of additional functional groups at the C-15 position-a hydroxyl group in compound 2 and isomeric isoprene units in compounds 3 and 4-might be responsible for the reduction in the potential/selectivity. In silico studies show, for compounds 1-4, good predictions regarding bioavailability and ADME (absorption, distribution, metabolism, and excretion) properties as well as no alerts for PAINS (pan-assay structures interference). In conclusion, ent-kaurenoic acid (1), a common diterpenoid isolated in high amounts from different plants belonging to the Baccharis genus, has been shown to be a promising cytotoxic agent against an aggressive adenocarcinoma cell line (MDA-MB-23) and, if well exploited, could be used as a scaffold in the development of molecular prototypes for the treatment of breast cancer.

Abstract
Human African trypanosomiasis (sleeping sickness) and American trypanosomiasis (Chagas disease) are vector-borne neglected tropical diseases, caused by the protozoan parasites Trypanosoma brucei and Trypanosoma cruzi, respectively. These diseases were circumscribed to South American and African countries in the past. However, human migration, military interventions, and climate changes have had an important effect on their worldwide propagation, particularly Chagas disease. Currently, the treatment of trypanosomiasis is not ideal, becoming a challenge in poor populations with limited resources. Exploring natural products from higher plants remains a valuable approach to find new hits and enlarge the pipeline of new drugs against protozoal human infections. This review covers the recent studies (2016–2021) on plant terpenoids, and their semi-synthetic derivatives, which have shown promising in vitro and in vivo activities against Trypanosoma parasites.

Abstract
Antimicrobial resistance has been posing an alarming threat to the treatment of infectious diseases over the years. Ineffectiveness of the currently available synthetic and semisynthetic antibiotics has led the researchers to discover new molecules with potent antimicrobial activities. To overcome the emerging antimicrobial resistance, new antimicrobial compounds from natural sources might be appropriate. Secondary metabolites from natural sources could be prospective candidates in the development of new antimicrobial agents with high efficacy and less side effects. Among the natural secondary metabolites, diterpenoids are of crucial importance because of their broad spectrum of antimicrobial activity, which has put it in the center of research interest in recent years. The present work is aimed at reviewing recent literature regarding different classes of natural diterpenes and diterpenoids with significant antibacterial, antifungal, antiviral, and antiprotozoal activities along with their reported structure–activity relationships. This review has been carried out with a focus on relevant literature published in the last 5 years following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 229 diterpenoids from various sources like plants, marine species, and fungi are summarized in this systematic review, including their chemical structures, classification, and significant antimicrobial activities together with their reported mechanism of action and structure–activity relationships. The outcomes herein would provide researchers with new insights to find new credible leads and to work on their synthetic and semisynthetic derivatives to develop new antimicrobial agents.

Ent-kaurane diterpenes isolated from n-hexane extract of Baccharis sphenophylla by bioactivity-guided fractionation target the acidocalcisomes in Trypanosoma cruzi. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 93:153748. [PMID: 34628240 DOI: 10.1016/j.phymed.2021.153748] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 09/09/2021] [Accepted: 09/10/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND In the present work the bioactivity-guided fractionation of n-hexane extract from aerial parts of Baccharis sphenophylla (Asteraceae) against trypomastigote forms of Trypanosoma cruzi was performed. PURPOSE To evaluate the antitrypanosomal potential of diterpenes ent‑kaurenoic (1), grandifloric (2). and 15β-tiglinoyloxy‑ent-kaurenoic (3) acids, isolated from n-hexane extract from aerial parts of B. sphenophylla, and elucidate their mechanism of action against T. cruzi. METHODS/STUDY DESIGN: n-Hexane and MeOH extracts from aerial parts of B. sphenophylla were prepared and caused, respectively, 100% and 50% of death of trypomastigote forms of T. cruzi. Based on these results, the n-hexane extract was subjected to bioactivity-guided fractionation procedures to afford three related ent‑kaurane diterpenoids (1-3). Based on spectrofluorometric assays and flow cytometry analysis, the mechanism of action of compounds 1 and 3 was investigated. RESULTS Compounds 1 and 3, isolated from n-hexane extract from aerial parts of B. sphenophylla, showed potent activity against parasites with EC50 values of 10.6 μM (SI > 18.8) and 2.4 μM (SI = 34.8), respectively. On the other hand, compound 2 was inactive against trypomastigotes. In mechanism of action studies using the fluorescent probe SYTOX Green, the plasma membrane permeability was unaltered after treatment with compounds 1 and 3, but compound 1 induced a depolarization of the plasma membrane electric potential (ΔΨp). No substantial alterations were observed in the mitochondria after treatment with compound 3, but a transient hyperpolarization of the mitochondrial membrane potential (ΔΨm) by compound 1. Despite the increased ATP levels induced by compounds 1 and 3, no alterations of ROS and Ca2+ levels were registered. However, both compounds promoted a time-dependent alkalinization of the acidocalcisomes, probably contributing to an osmotic imbalance of the cell. In silico physicochemical studies of compounds 1-3 suggested that lipophilicity and molecular complexity may play an important role in the antitrypanosomal activity. Moreover, no pan-assay interference compounds (PAINS) alerts were detected for compounds 1-3. CONCLUSION Obtained data indicated that the isolated ent‑kaurane diterpenes from n-hexane extract from aerial parts of B. sphenophylla, especially compound 3, could be considered interesting prototypes for further modifications aiming the discovery of new hits against T. cruzi.

Abstract
The hexane extract from aerial parts Baccharis sphenophylla Dusén ex Malme (Asteraceae) displayed activity against amastigote forms of Trypanossoma cruzi and was subjected to chromatographic steps to afford one unreported - 7α-hydroxy-ent-abieta-8(14),13(15)-dien-16,12β-olide (1) and three known diterpenes - ent-kaur-16-en-19-oic acid, (2), grandifloric acid (3), and 15β-tiglinoyloxy-ent-kaur-16-en-19-oic acid (4), two sesquiterpenes - spathulenol (5) and oplopanone (6) - as well as hexacosyl p-coumarate (7). Isolated compounds were characterized by NMR and ESI-HR-MS spectra and were evaluated in vitro for activity against amastigote forms of the parasite T. cruzi - the relevant clinical form in the chronic phase of Chagas disease. In addition, the activity of compounds 1-7 against NCTC cells was evaluated. Compounds 1 and 7 showed effectiveness with EC50 values of 21.3 and 16.9 μM, respectively. Both compounds also exhibited reduced toxicity against NCTC cells (CC50 >200 μM) with SI values higher than 9.4 and 11.9. Obtained results suggest that the new ent-abietane diterpene 1 and alkyl coumarate 7 could be used as prototypes for the development of novel and selective semisynthetic derivatives against intracellular forms of T. cruzi.

Abstract
Praziquantel is the only available drug to treat schistosomiasis, and therefore, urgent studies must be performed to identify new anthelmintic agents. This study reports the anthelmintic evaluation of two related ent-kaurane diterpenes isolated from aerial parts of Baccharis lateralis (Asteraceae), ent-kaur-16-en-19-oic acid (1) and 15β-senecioyl-oxy-ent-kaur-16-en-19-oic acid (2) against Schistosoma mansoni in vitro and in a murine model of schistosomiasis. Both compounds exhibited in vitro activity with lethal concentration 50% (LC50) values of 26.1 μM (1) and 11.6 μM (2) as well as reduced toxicity against human cell lines, revealing a good selectivity profile, mainly with compound 2 (selectivity index > 10). Compound 2 also decreased egg production and caused morphological alterations in the parasite reproductive system. In mice infected with S. mansoni, oral treatment with compound 2 at 400 mg/kg, the standard dose used in this model of schistosomiasis, caused a significant reduction in a total worm burden of 61.9% (P < 0.01). S. mansoni egg production, a key mechanism for both transmission and pathogenesis, was also markedly reduced. In addition, compound 2 achieved a significant reduction in hepatosplenomegaly. Therefore, the diterpene 15β-senecioyl-oxy-ent-kaur-16-en-19-oic acid (2) has an acceptable cytotoxicity profile and is orally active in a murine schistosomiasis model.

Abstract
As part of the search for anti-trypanosomal agents, this work presents the production of sixteen derivatives. All of them were obtained from two natural diterpenes, one with kaurane skeleton (ent-kaurenoic acid) and other with a pimarane skeleton (ent-pimaradienoic acid). Then, the eighteen compounds were assayed against epimastigote form of Trypanosoma cruzi, with the derivatives showing increase of activity in relation to their precursors. Moreover, the most active derivative presented an IC50 <12.5 µM (estimated 0.8 µM), lower than Benznidazole (IC50 = 9.8 µM), used as control. The esterification of acid diterpenes showed to be an interesting way in the search for anti-trypanosomal agents.

Abstract
Background: Visceral leishmaniasis is a complex neglected tropical disease caused by
Leishmania donovani complex. Its current treatment
reveals strong limitations, especially high toxicity. In this context,
natural products are important sources of new drug alternatives for VL
therapy. Therefore, the antileishmanial and immunomodulatory activity of
compounds isolated from Nectandra oppositifolia (Lauraceae)
was investigated herein. Methods: The n-hexane extract from twigs of N.
oppositifolia were subjected to HPLC/HRESIMS and
bioactivity-guided fractionation to afford compounds 1 and
2 which were evaluated in vitro against
Leishmania (L.) infantum
chagasi and NCTC cells. Results: The n-hexane extract displayed activity against
L. (L.) infantum
chagasi and afforded isolinderanolide E
(1) and secosubamolide A (2),
which were effective against L. (L.)
infantum chagasi promastigotes, with IC50
values of 57.9 and 24.9 µM, respectively. Compound 2 was
effective against amastigotes (IC50 = 10.5 µM) and displayed
moderate mammalian cytotoxicity (CC50 = 42 µM). The
immunomodulatory studies of compound 2 suggested an
anti-inflammatory activity, with suppression of IL-6, IL-10, TNF with lack
of nitric oxide. Conclusion: This study showed the antileishmanial activity of compounds 1
and 2 isolated from N. oppositifolia.
Furthermore, compound 2 demonstrated an antileishmanial
activity towards amastigotes associated to an immunomodulatory effect.

Abstract
The MeOH extract from leaves of Saururus cernuus L. (Saururaceae) displayed in vitro activity against trypomastigote forms of T. cruzi (100% of parasite death at 200 μg/mL), suggesting the presence of bioactive compounds. Thus, the bioactivity-guided fractionation was carried out, leading to the isolation of three related neolignan derivatives, identified as threo-austrobailignan-5 (1), threo-austrobailignan-6 (2), and threo-dihydroguaiaretic acid (3). Anti-T. cruzi activity of compounds 1-3 was performed against cell-derived trypomastigotes and intracellular amastigotes. Additionally, the mammalian cytotoxicity was investigated using NCTC cells. Compound 2 was the most effective against extracellular trypomastigotes with IC50 of 3.7 μM, while compound 3 showed activity in both clinically relevant forms of the parasite, trypomastigotes and amastigotes, with IC50 values of 7.0 and 16.2 μM, respectively. However, the structurally related compound 1 was inactive. Based on these results, compounds 2 and 3 were selected to evaluate the mechanism of cellular death. Compound 2 induced alteration in the plasma membrane permeability and consequently in the ROS levels after 120 min of incubation. By using flow cytometry and fluorescence microscopy, compound 3 showed alterations in the mitochondrial membrane potential (ΔΨm) of trypomastigotes. Considering the promising chemical and biological properties of neolignans 2 and 3, these compounds could be used as starting points to develop new lead compounds for Chagas disease.

Abstract
Leishmaniasis and Chagas disease cause great impact on social and economic aspects of people living in developing countries. The treatments for these diseases are based on the same regimen for over 40 years, thus, there is an urgent need for the development of new drugs. In this scenario, Asteraceae plants (a family widely used in folk medicine worldwide) are emerging as an interesting source for new trypanocidal and leishmanicidal compounds. Herein, we provide a non-exhaustive review about the activity of plant-derived products from Asteraceae with inhibitory action toward Leishmania spp. and T. cruzi. Special attention was given to those studies aiming the isolation (or identification) of the bioactive compounds. Ferulic acid, rosmarinic acid, and ursolic acid (Baccharis uncinella DC.) were efficient to treat experimental leishmaniasis; while deoxymikanolide (Mikania micrantha) and (+)-15-hydroxy-labd-7-en-17-al (Aristeguietia glutinosa Lam.) showed in vivo anti-T. cruzi action. It is also important to highlight that several plant-derived products (compounds, essential oils) from Artemisia plants have shown high inhibitory potential against Leishmania spp., such as artemisinin and its derivatives. In summary, these compounds may help the development of new effective agents against these neglected diseases.

Abstract
In the present study, a series of new esters of secochiliolide acid (SA), a diterpene isolated from Nardophyllum bryoides, were synthesized in good yield. All compounds were evaluated for their in vitro antiparasitic properties (on Plasmodium falciparum and Trypanosoma brucei brucei) and cytotoxicity (on WI38, normal mammalian cells). They displayed moderate antitrypanosomal activity with IC50 values between 2.55 and 18.14 μm, with selectivity indices >10, and low antiplasmodial effects with IC50 > 29 μm. The only exception was the n-hexyl ester of SA, which showed a strong and selective antiplasmodial activity (IC50 = 1.99 μm and selectivity index = 117.0). The in vivo antimalarial efficacy of this compound was then assessed according to the 4-day suppressive test of Peters in mice. An intraperitoneal treatment at 50 mg kg-1 day-1 induced a slight parasitaemia reduction by 56% which was statistically significant on day 4 post-infection and an increase in the survival time.
