1.Efficient expression of single chain variable fragment antibody against paclitaxel using the Bombyx mori nucleopolyhedrovirus bacmid DNA system and its characterizations.
Yusakul G;Sakamoto S;Tanaka H;Morimoto S J Nat Med. 2016 Jul;70(3):592-601. doi: 10.1007/s11418-016-0981-5. Epub 2016 Mar 3.
A single chain variable fragment (scFv), the smallest unit of functional recombinant antibody, is an attractive format of recombinant antibodies for various applications due to its small fragment and possibility of genetic engineering. Hybridoma clone 3A3 secreting anti-paclitaxel monoclonal antibody was used to construct genes encoding its variable domains of heavy (VH) and light (VL) chains. The VH and VL domains were linked to be the PT-scFv3A3 using flexible peptide linker in a format of VH-(GGGGS)5-VL. The PT-scFv3A3 was primarily expressed using the pET28a(+) vector in the Escherichia coli system, and was then further expressed by using the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid DNA system. Interestingly, the reactivity of PT-scFv3A3 expressed in the hemolymph of B. mori using the BmNPV bacmid DNA system was much higher than that expressed in the E. coli system. Using indirect competitive enzyme-linked immunosorbent assay (icELISA), the PT-scFv3A3 (B. mori) reacted not only with immobilized paclitaxel, but also with free paclitaxel in a concentration-dependent manner, with the linear range of free paclitaxel between 0.156 and 5.00 µg/ml. The PT-scFv3A3 (B. mori) exhibited less cross-reactivity (%) than its parental MAb clone 3A3 against paclitaxel-related compounds, including docetaxel (31.
2.Studies on chemical constituents of planted Taxus mairei (III).
Chen XY;Liang JY Yao Xue Xue Bao. 2008 Dec;43(12):1205-7.
From the chloroform-soluble fraction of the ethanol extracts of the whole plant of Taxus chinensis var. mairei (Lemee et Lev1), four compounds were isolated by using repeated column chromatography on silica gel and Sephadex LH-20. Based on spectroscopic data (UV, IR, ESI-MS, 1H NMR and 13C NMR), the compounds were identified as taxamairin K (1), 2alpha, 4alpha-dideacetoxy-7beta-benzoyloxy-5beta,20-epoxy-9alpha, 10beta, 13alpha, 15-tetrahydroxy-11(15-->1) abeotaxa-11-ene (2), 7beta-xylosyl-taxol (3), 10-deacetoxy-7-xylosyl-taxol (4). Among them, taxamairin K is a new compound.
3.[Content and distribution of active components in cultivated and wild Taxus chinensis var. mairei plants].
Yu SS;Sun QW;Zhang XP;Tian SN;Bo PL Ying Yong Sheng Tai Xue Bao. 2012 Oct;23(10):2641-7.
Taxus chinensis var. mairei is an endemic and endangered plant species in China. The resources of T. chinensis var. mairei have been excessively exploited due to its anti-cancer potential, accordingly, the extant T. chinensis var. mairei population is decreasing. In this paper, ultrasonic extraction and HPLC were adopted to determine the contents of active components paclitaxel, 7-xylosyltaxol and cephalomannine in cultivated and wild T. chinensis var. mairei plants, with the content distribution of these components in different parts of the plants having grown for different years and at different slope aspects investigated. There existed obvious differences in the contents of these active components between cultivated and wild T. chinensis var. mairei plants. The paclitaxel content in the wild plants was about 0.78 times more than that in the cultivated plants, whereas the 7-xylosyltaxol and cephalomannine contents were slishtly higher in the cultivated plants. The differences in the three active components contents between different parts and tree canopies of the plants were notable, being higher in barks and upper tree canopies. Four-year old plants had comparatively higher contents of paclitaxel, 7-xylosyltaxol and cephalomannine (0.
