Abstract
The new natural products reported in 2022 in peer-reviewed articles in journals with good reputations were reviewed and analyzed. The advances made by Asian research groups in the field of natural products chemistry in 2022 were summarized. Compounds with unique structural features and/or promising bioactivities originating from Asian natural sources were discussed based on their structural classification.

Lu Y, Xu Q, Pang L, Liu Y, Li L, Yan J, Zhang Y, Huang Z. HMG-CoA reductase inhibitor from the endophytic fungus Colletotrichum Capsici. Nat Prod Res 2023:1-9. [PMID: 38105709 DOI: 10.1080/14786419.2023.2289085] [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: 07/05/2023] [Accepted: 11/23/2023] [Indexed: 12/19/2023]
Abstract
Two new fungal polyketides with unusual skeleton, collecapsins A and B (1-2), along with two known macrolactins A and B (3-4), were isolated from the rice cultures of an endophytic fungus Colletotrichum capsici obtained from the fresh Siegesbeckia pubescens Makino. Their structures were established by a combination of NMR, HRESIMS, and IR analysis. The absolute configurations of 1 and 2 were determined on the detailed analysis of the modified Mosher's derivatives' spectra and its key NOEs correlations. In this case, the absolute configurations of all chiral centres of 1 were determined for the first time, showed that 1 is a C-6/C-8 epimer of colletruncoic acid methyl ester. Compounds 1-2 demonstrated promising lipid lowing activity via the inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase with IC50 values of 8.72 and 15.28 μM. Compounds 3-4 exhibited antibacterial activity with MIC values ranging from 0.25-25.8 μM.

Prenyllongnols A-D, New Prenylated Acylphloroglucinols that Fight Concanavalin A-Induced Autoimmune Hepatitis. JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2023; 71:17801-17809.

Abstract
Autoimmune hepatitis is a serious hepatic disorder with unknown nosogenesis, and natural products have been deemed to be one of the most significant sources of new drugs against this disease. Prenyllongnols A-D (1-4), four undescribed prenylated acylphloroglucinols, were isolated from Hypericum longistylum. Compounds 1-4 exhibited remarkable immunosuppressive activities in murine splenocyte proliferation under the induction of concanavalin A (Con A), and IC50 values ranged from 2.98 ± 0.21 to 6.34 ± 0.72 μM. Furthermore, in a Con A-challenged autoimmune hepatitis mouse model, the mice in the group that were pretreated with isolate 2 significantly ameliorated liver injury and decreased proinflammatory cytokine production. Notably, natural product 2 was the first prenylated acylphloroglucinol to protect against concanavalin A-induced autoimmune hepatitis. This finding underscores the potential of prenylated acylphloroglucinol-type metabolites as promising candidates for designing novel immunosuppressors in the quest for new antiautoimmune hepatitis drugs.
