Abstract
The diterpenoid alkaloids are a family of extremely important natural products that have long been a research hotspot due to their myriad of intricate structures and diverse biological properties. This chapter systematically summarizes the past 11 years (2009-2019) of studies on the diterpenoid alkaloids, including the "so-called" atypical ones, covering the classification and biogenetic relationships, phytochemistry together with 444 new alkaloids covering 32 novel skeletons and the corrected structures, chemical reactions including conversion toward toxoids, synthetic studies, as well as biological activities. It should be noted that the synthetic studies, especially the total syntheses of various diterpenoid alkaloids, are for the first time reviewed in this treatise. This chapter, in combination with our four previous reviews in volumes 42, 59, 67, and 69, will present to the readers a more completed and updated profile of the diterpenoid alkaloids.

[PMID: 34628107 DOI: 10.1016/j.phytochem.2021.112971] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Revised: 09/24/2021] [Accepted: 09/25/2021] [Indexed: 06/13/2023]
Abstract
Six undescribed diterpenoid alkaloids including five C19-diterpenoid alkaloids forrestlines A-E, and one C20-diterpenoid alkaloid forrestline F, together with nine known alkaloids have been isolated from the whole herbs of Delphinium forrestii var. vride. Their structures were elucidated by spectroscopic data, and their inhibitory activities on NO production stimulated by LPS in RAW264.7 macrophage cells were determined. Then, forrestline F, with the strongest inhibitory activity (IC50 of 9.57 ± 1.43 μM), was selected to study its possible anti-inflammatory mechanism. ELISA results showed that forrestline F suppressed inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosisfactor-α (TNF-α), and interleukin-6 (IL-6). Moreover, forrestline F could down-regulate LPS-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) by western blotting assay. It also inhibited expression of phosphorylation of MAPKs (including p-p38, p-ERK and p-JNK), and NF-κB p65, and decreased ROS accumulation by upregulating the expression of HO-1 expression via nuclear translocation of Nrf2. In conclusion, forrestline F showed anti-inflammatory effect by inhibiting NF-κB/MAPK and Nrf2/HO-1 signaling pathway. Therefore, forrestline F could be a promising molecule for the development of anti-inflammatory agents in the future.

Abstract
Covering: 2009 to 2018. Diterpenoid alkaloids, originating from the amination of natural tetracyclic diterpenes, are a diverse class of compounds having complex structural features with many stereocenters. The important pharmacological activities and structural complexity of the diterpenoid alkaloids have long interested scientists due to their medicinal uses, infamous toxicity, and unique biosynthesis. Since 2009, 373 diterpenoid alkaloids, assigned to 46 skeletons, have been isolated and identified from plants mostly in the Ranunculaceae family. The names, classes, molecular weight, molecular formula, NMR data, and plant sources of these diterpene alkaloids are collated here. This review will be a detailed update of the naturally occurring diterpene alkaloids reported from the plant kingdom from 2009-2018, providing an in-depth discussion of their diversity, biological activities, pharmacokinetics, toxicity, application, evolution, and biosynthesis.

Abstract
Diterpenoid alkaloids are natural compounds having complex structural features with many stereo-centres originating from the amination of natural tetracyclic diterpenes and produced primarily from plants in the Aconitum, Delphinium, Consolida genera. Corals, Xenia, Okinawan/Clavularia, Alcyonacea (soft corals) and marine sponges are rich sources of diterpenoids, despite the difficulty to access them and the lack of availability. Researchers have long been concerned with the potential beneficial or harmful effects of diterpenoid alkaloids due to their structural complexity, which accounts for their use as pharmaceuticals as well as their lousy reputation as toxic substances. Compounds belonging to this unique and fascinating family of natural products exhibit a broad spectrum of biological activities. Some of these compounds are on the list of clinical drugs, while others act as incredibly potent neurotoxins. Despite numerous attempts to prepare synthetic products, this review only introduces the natural diterpenoid alkaloids, describing 'compounds' structures and classifications and their toxicity and bioactivity. The purpose of the review is to highlight some existing relationships between the presence of substituents in the structure of such molecules and their recognised bioactivity.

Abstract
Five new aconitine-type C19-diterpenoid alkaloids, apetalrines A-E (1-5), were isolated from Aconitum apetalum. Their structures were determined by analysis of 1D and 2D NMR, IR, and HRESIMS data. Semisynthesis of apetalrine B (2) from its parent compound aconorine was achieved to confirm the structure proposed. Twenty derivatives of 2 (11a-11l, 12a, 12b, 12d, 12e, 12j, 12k, 12m, 12n) were synthesized via a unified approach relying on simple coupling reactions. The evaluation of neuroprotective effects of compounds (1-5, 11b, 11c, 11f-11i, 12a, 12b, 12d, 12e, 12k, 12m, 12n) with low cytotoxicity revealed compound 2 to exhibit good neuroprotective effects in H2O2-treated SH-SY5Y cells at a concentration of 50 μM. A series of studies using flow cytometry, staining, and Western blotting on 2 indicated that its neuroprotective effects may arise from inhibiting cell apoptosis.

Abstract
Seven new anthranilamide derivatives, acoapetalines A-G (1-7), including one new naturally occurring compound (7), together with six known ones (8-13) were isolated from the whole plants of Aconitum apetalum. Their structures were established on the basis of extensive spectroscopic analyses (IR, UV, HRESIMS, 1D and 2D NMR). All compounds were evaluated for their anti-tobacco mosaic virus (anti-TMV) activities. The results showed that compound 10 exhibited significant anti-TMV activity with an inhibition rate of 67.57% (100 μg/mL), which was higher than that of ningnamycin (52.89%).
