Abstract
From a CH2 Cl2 -soluble fraction of the stem barks of Taxus wallichiana, one new abeo-icetexane-type diterpenoid, taxamairin I (1), was isolated. Its absolute configuration was elucidated based on spectroscopic interpretation and time-dependent density functional theory (TD-DFT) calculation of optical rotation. In addition, the plausible biosynthesis pathway for the formation of the new abeo-icetexane-type diterpenoid was proposed. Taxamairin I (1), at a concentration of 100 μM, did not show cytotoxicity against Hep3B human liver cancer cell lines.

de S Vargas F, D O de Almeida P, Aranha ESP, de A Boleti AP, Newton P, de Vasconcellos MC, Junior VFV, Lima ES. Biological activities and cytotoxicity of diterpenes from Copaifera spp. Oleoresins. Molecules 2015; 20:6194-210. [PMID: 25859778 PMCID: PMC6272497 DOI: 10.3390/molecules20046194] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 04/01/2015] [Accepted: 04/02/2015] [Indexed: 12/02/2022] Open
Abstract
Copaifera spp. are Amazonian species widely studied and whose oleoresins are used by local people for various medicinal purposes. However, a detailed study of the activity of the main phytochemical components of these oleoresins remains to be done. Here, we studied the cytotoxicity and in vitro anti-inflammatory effects of six diterpene acids: copalic, 3-hydroxy-copalic, 3-acetoxy-copalic, hardwickiic, kolavic-15-metyl ester, and kaurenoic, isolated from the oleoresins of Copaifera spp. The diterpenes did not show cytotoxicity in normal cell lines, nor did they show significant changes in viability of tumoral line cells. The 3-hydroxy-copalic was able to inhibit the enzyme tyrosinase (64% ± 1.5%) at 250 µM. The kolavic-15-metyl ester at 200 µM showed high inhibitory effect on lipoxygenase (89.5% ± 1.2%). Among the diterpenes tested, only kaurenoic and copalic acids showed significant hemolytic activities with 61.7% and 38.4% at 100 µM, respectively. In addition, it was observed that only the copalic acid (98.5% ± 1.3%) and hardwickiic acid (92.7% ± 4.9%) at 100 mM inhibited nitric oxide production in macrophages activated by lipopolysaccharide. In this assay, the diterpenes did not inhibit tumor necrosis factor-α production. The acids inhibited the production of IL-6, 3-acetoxy-copalic (23.8% ± 8.2%), kaurenoic (11.2% ± 5.7%), kolavic-15-methyl ester (17.3% ± 4.2%), and copalic (4.2% ± 1.8%), respectively, at 25 µM. The kaurenoic, 3-acetoxy-copalic and copalic acids increased IL-10 production. This study may provide a basis for future studies on the therapeutic role of diterpenic acids in treating acute injuries such as inflammation or skin disorders.

Abstract
Transformation of Finasteride (I) by cell suspension cultures of Ocimum sanctum L. was investigated. Fermentation of compound (I) with O. sanctum afforded three oxidized derivatives, 16β-hydroxyfinasteride (II), 11α-hydroxyfinasteride (III) and 15β-hydroxyfinasteride (IV). Among these metabolites, compound (II) was a new metabolite. Compound (I) and its derivatives were studied for their tyrosinase inhibition assay. All test compounds exhibited significant activity compared to standard drug kojic acid, with compound IV being the most potent member with an IC50 of 1.87μM. Molecular docking revealed significant molecular interactions behind the potent tyrosinase inhibitory activity of the tested compounds.
