您要查找的是不是：
- 去乙酰头孢菌素C（DCPC） deacetyl cephalosporin C ( DCPC )
- 在经纳滤膜浓缩后,通过弱碱性离子交换树脂Amberlite IRA67吸附,以0.5mol/L醋酸钠缓冲液洗脱,得到DAC纯度95%,含量大于30g/L的去乙酰头孢菌素C的钠盐溶液,收率在90~95%。 After the eluate was concentrated by Nanofilter membrane, it was passed through a column packed with the resin of Amberlite IRA67, a weakly basic ion-exchange resin on which DAC was adsorbed.
- 去乙酰头孢菌素C deacetylcephalosporinC
- 去乙酰头孢菌素 desacetylcephalothin
- 氰乙酰头孢菌素 cephacetrile
- 脱乙酰氧基头孢菌素C合酶 deacetoxycephalosporin C synthase
- 足叶乙甙(etoposide)及阿霉素(doxorubicin)能诱导胃癌细胞凋亡及BGC-823 PARP裂解的发生,wortmannin可以增强其作用。 Etoposide and doxorubicin could induce gastric carcinoma cell apoptosis and split of the poly ADP-ribose polymerase protein in BGC-823 cells,wortmannin could enhance the effect.
- a、C-3位直接与双键相连的头孢菌素衍生物：分别以“分步法”与“一锅法”采用魏悌锡(Wittig)反应合成了(6R,7R)-7-苯乙酰氨基-8-氧代-5-硫-1-氮杂双环[4.2.0]辛-2-烯-3-乙烯基-2-羧酸二苯甲基酯(8)。 Diphenylmethyl(6R,7R)-8-oxo-7-(phenylacetyl)amino-3-vinyl-5-thia-l-azabicyclo[4.2.0] oct-2-ene-2-carboxylate(8) were synthesized according to Wittig Reaction via fractional step method and one-pot process separately.
