Saturated fatty acyl CoAs with a carbon chain length of 14, 16 and 18 exhibited higher yields than those with a carbon chain length of 10 or 12. Acyl CoAs with carbon chain lengths from 14 to 18 and containing either a diene unit, an alkyne unit, or an azide unit in the carbon chain were synthesized and shown to provide the corresponding DTX3 with a yield comparable to that of hexadecanoyl CoA. The three
冈果酸(原鞭毛原鞭毛体物种的产物)在各种双壳类动物中被转化为7- O-酰基OA。在存在来自双壳类动物消化腺的微粒体级分的情况下,结构转化在体外以酶促方式进行。我们一直在使用LC-MS / MS通过检测7- O来鉴定OA转化酶-酰基OA,也称为dinophysistoxin 3(DTX3)。但是,由于OA转化酶是一种膜蛋白,而DTX3的替代测定是必需的,而溶解膜蛋白的表面活性剂会降低LC-MS / MS的灵敏度。本研究研究了饱和脂肪酰基CoA,其碳链长度为10(癸酰基),12(十二烷酰基),14(十四烷酰基),16(十六烷酰基)和18(十八烷酰基)为体外酰化反应的底物。碳链长度为14、16和18的饱和脂肪酰基CoA的收率高于碳链长度为10或12的饱和脂肪酰基CoA。碳链长度为14至18且包含二烯单元,炔烃单元的酰基CoA ,合成或显示出碳链中的叠氮单元或叠氮化物单元,并显示出可提供与十六烷酰
