Abstract
The discovery of naturally occurring organohalogen compounds has increased astronomically in the 55 years since they were first discovered─from fewer than 50 in 1968 to a combined 7,958 described examples in three comprehensive reviews. The present survey, which covers the period 2021-2023, brings the number of known natural organohalogens to approximately 8,400. The organization is according to species origin, and coverage includes marine and terrestrial plants, fungi, bacteria, marine sponges, corals, cyanobacteria, tunicates, and other marine organisms.

Abstract
Guided by the Global Natural Products Social (GNPS) molecular networking strategy, five undescribed eremophilane-type sesquiterpenoid derivatives (1-5) were isolated and identified from fungus Penicillium roqueforti, which was separated from the root soil of plant Hypericum beanii collected in Shennongjia Forestry District, Hubei Province. Dipeniroqueforins A-B (1-2), representing a lactam-type sesquiterpenoid skeleton with a highly symmetrical and homodimeric 5/6/6-6/6/5 hexacyclic system, are reported within the eremophilane-type family for the first time. Peniroqueforin D (5) represents the first example of a 1,2-seco eremophilane-type sesquiterpenoid derivative featuring an undescribed 7/6-fused ring system. The structures of these compounds were elucidated by various spectroscopic analyses, DP4+ probability analyses, ECD calculations, and single-crystal X-ray diffraction experiments. Furthermore, these isolates were evaluated for cytotoxicity, and the result uncovered that compound 1 displayed broad-spectrum activity. Further mechanistic study revealed that compound 1 could significantly upregulate the mRNA expression of genes related to the oxidative induction, leading to the abnormal ROS levels in tumor cells and ultimately causing tumor cell apoptosis.

Qin LF, Gao HH, Zhang X, Yuan X, Feng ZM, Zhang PC, Jiang JS, Yang YN. Seventeen undescribed iridoid derivatives with anti-inflammatory effects from Hedyotis diffusa and their structure-activity relationships. PHYTOCHEMISTRY 2024; 217:113904. [PMID: 37926152 DOI: 10.1016/j.phytochem.2023.113904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/09/2023] [Accepted: 10/22/2023] [Indexed: 11/07/2023]
Abstract
Seventeen undescribed iridoid derivatives (1-17) and four known compounds (18-21) were isolated from the whole plant of Hedyotis diffusa Willd. Their structures were elucidated based on unambiguous spectroscopic data (UV, IR, HRESIMS, CD, and 1D and 2D NMR). It is noteworthy that compounds 1-8, which possess unique long-chain aliphatic acid moiety, were reported for the first time among the iridoid natural products. All compounds were evaluated for their anti-inflammatory activities in lipopolysaccharide-induced RAW 264.7 cells. Compounds 2, 4, and 6 showed significant suppression effects on nitric oxide production, with IC50 values of 5.69, 6.16, and 6.84 μM, respectively. The structure-activity relationships of these compounds indicated that long-chain aliphatic moieties at C-10 might be the key group for their anti-inflammatory activities. The therapeutic properties of these iridoid derivatives could give an insight into utilizing H. diffusa as a natural source of anti-inflammatory agents.

Abstract
Melanoma is a highly aggressive and life-threatening form of skin cancer that accounts for a significant proportion of cancer-related deaths worldwide. Although conventional cancer therapies, such as surgical excision, chemotherapy, and radiation, have been used to treat malignant melanoma, their efficacy is often limited due to the development of resistance and adverse side effects. Therefore, there is a growing interest in developing alternative treatment options for melanoma that are more effective and less toxic. Terpenes, a diverse group of naturally occurring compounds of plant origin, have emerged as potential anticancer agents due to their ability to inhibit tumor growth and induce apoptosis in cancer cells. In this review, the current understanding of the anticancer effects of terpenes (including, thymoquinone, β-elemene, carvacrol, limonene, α-pinene, β-caryophyllene, perillyl alcohol, taxol, betulinic acid, α-bisabolol, ursolic acid, linalool, lupeol, and artesunate) was summarized, with a special focus on their potential as therapeutic agents for malignant melanoma.
