Determination of Absolute Configuration and Biological Activity of New Immunosuppressants, Mycestericins D, E, F and G.
摘要:
Mycestericins D、E、F 和 G 是从 Mycelia sterilia ATCC 20349 的培养液中分离出的强效免疫抑制剂。Mycestericins F 和 G 分别与二氢美克斯特里辛 D 和 E 相同。通过使用修饰的 MOSHER 方法和比较它们的苯甲酸酯衍生物的圆二色光谱与合成类似物的光谱,确定了它们的绝对构型。Mycestericins D、E、F 和 G 抑制了小鼠同种异体混合淋巴细胞反应中淋巴细胞的增殖。

The invention provides immunostimulatory compositions comprising a small molecule immuno-potentiator (SMIP) compound and methods of administration thereof. Also provided are methods of administering a SMIP compound in an effective amount to enhance the immune response of a subject to an antigen. Further provided are novel compositions and methods of administering SMIP compounds alone or in combination with another agent for the treatment of cancer, infectious diseases and/or allergies/asthma. In a further aspect, the invention relates generally to methods of screening for small molecule immuno-modulatory compositions.
