Reference Reading
1. Capsimycin, a new antibiotic. I. Production, isolation and properties
S Aizawa, H Akutsu, T Satomi, T Nagatsu, R Taguchi, A Seino J Antibiot (Tokyo). 1979 Mar;32(3):193-6. doi: 10.7164/antibiotics.32.193.
Capsimycin is a new antifungal antibiotic produced by a strain of Streptomyces sp. C 49--87. The active substance in the fermented broth was isolated by solvent extraction followed by silica gel column chromatography. The antibiotic melts at 186 degrees C (decomp.) and has a molecular formula C30H40N2O6. It exhibits marked inhibitory activity against Phytophthora capsici (Leaf blight disease of cucumber) and Pythium debaryanum (Damping-off disease of cucumber).
2. Screening for apoptosis inducers in microbial products and induction of apoptosis by cytostatin
K Yamazaki, M Amemiya, M Ishizuka, T Takeuchi J Antibiot (Tokyo). 1995 Oct;48(10):1138-40. doi: 10.7164/antibiotics.48.1138.
We have employed the DNA-methylgreen binding assay as a primary screening method for identifying apoptosis inducers in microbial products. Capsimycin, toyocamycin and cytostatin affect the binding of methylgreen to DNA of FS3 cells in this test system. The effect of cytostatin on apoptosis induction was confirmed by means of the ELISA system.
3. Structural diversity of anti-pancreatic cancer capsimycins identified in mangrove-derived Streptomyces xiamenensis 318 and post-modification via a novel cytochrome P450 monooxygenase
He-Lin Yu, Shu-Heng Jiang, Xu-Liang Bu, Jia-Hua Wang, Jing-Yi Weng, Xiao-Mei Yang, Kun-Yan He, Zhi-Gang Zhang, Ping Ao, Jun Xu, Min-Juan Xu Sci Rep. 2017 Jan 18;7:40689. doi: 10.1038/srep40689.
Polycyclic tetramate macrolactams (PTMs) were identified as distinct secondary metabolites of the mangrove-derived Streptomyces xiamenensis 318. Together with three known compounds-ikarugamycin (1), capsimycin (2) and capsimycin B (3)-two new compounds, capsimycin C (4) with trans-diols and capsimycin D (5) with trans-configurations at C-13/C-14, have been identified. The absolute configurations of the tert/tert-diols moiety was determined in 4 by NMR spectroscopic analysis, CD spectral comparisons and semi-synthetic method. The post-modification mechanism of the carbocyclic ring at C-14/C-13 of compound 1 in the biosynthesis of an important intermediate 3 was investigated. A putative cytochrome P450 superfamily gene, SXIM_40690 (ikaD), which was proximally localized to the ikarugamycin biosynthetic pathway, was characterized. In vivo gene inactivation and complementation experiment confirmed that IkaD catalysed the epoxide-ring formation reaction and further hydroxylation of ethyl side chain to form capsimycin G (3'). Binding affinities and kinetic parameters for the interactions between ikarugamycin (1) and capsimycin B (3) with IkaD were measured with Surface Plasmon Resonance. The intermediate compound 3' was isolated and identified as 30-hydroxyl-capsimycin B. The caspimycins 2 and 3, were transferred to methoxyl derivatives, 6 and 7, under acidic and heating conditions. Compounds 1-3 exhibited anti-proliferative activities against pancreatic carcinoma with IC50 values of 1.30-3.37 μM.
