A novel Salvialactomine from the callus culture of Salvia santolinifolia Boiss
Abstract A novel compound Salvialactomine (1) along with two other unusual occurring natural products Pentatriacontanoic acid 1, 3-dihydroxypropyl ester (2) and 5-Methylflavone (3) were isolated from the callus of Salvia santolinifolia Boiss. Callus was initiated on MS medium containing NAA (0.5 mg/L) and further sub-cultured on MS medium supplemented with NAA with BA (0.5 + 1.5 mg/L). The structures of isolated compounds were determined by using mass spectrometry, 1D, and 2D–NMR techniques. Compounds 1, and 3 were tested for two different cancer cell lines, i.e. Hela (Cervical cancer cell) and PC-3 (Prostate cancer cells). IC50 was found as > 30 using Doxorobicin (0.912 ± 0.12 μmol L−1) as a standard.
Callus Culture for the Production of Therapeutic Compounds
Plant-derived compounds retain a special place in the treatment of various diseases across the world. Their application cuts across every class of disease, where they are found to be often equal or of greater potency, safer and cheaper than so-called "orthodox" medicines. These advantages have led to great interest in the use of callus culture as a biotechnological tool for the harnessing of these useful therapeutic compounds. Callus culture techniques aim to increase the yield of active constituents in cultured plant cells and to produce novel products on a large scale. These techniques have been applied to produce various classes of therapeutic compounds from diverse plant species through empirical determination of ideal culture conditions and other methods. This review presents at a glance the recent advances being made in the field of callus culture for the production of therapeutic compounds, with the aim of showing that it is time for the full potentials of callus culture to be exploited on a scale that will prove a useful weapon in the arsenal of clinical therapeutics.
First diamino Daphniphyllum alkaloid, daphnipaxinin, with an unprecedented heterohexacyclic skeleton from Daphniphyllum paxianum.
[structure: see text] The first diamino Daphniphyllum alkaloid, daphnipaxinin (1), with an unprecedented hexacyclic fused skeleton, along with a known alkaloid, daphnicyclidin A (2), was isolated from the stem of Daphniphyllum paxianum Rosenth. The structure and absolute stereochemistry of 1 were established by spectral methods, especially two-dimensional NMR techniques and CD analysis.
