We investigated the effects of the active principle of lipopolysaccharide (LPS), synthetic lipid A (compound 506), and of its related compounds GLA-60, -59 and -27, on murine macrophage activation and cytokine induction. GLA-60, which is devoid of endotoxic activity, showed interleukin-1 (IL-1)-inducing activity and activation of murine macrophages comparable to those of LPS or compound 506. The biological activities of six conjugates of GLA-60 with MDP derivatives GMD-323 to -328 were investigated in this study. All the GMD compounds except GMD-323 showed potent inducing activities for IL-1 and tumoricidal macrophages, especially GMD-324 and -326, which exhibited much higher activity than GLA-60. However, TNF- and CSF-inducing activities of these conjugates were lower than those of GLA-60. IL-1-inducing activity of the mixture of MDP derivative (GMD-267) and GLA-60 was higher than that of the conjugates (GMD-324) or that of GLA-60 and GMD-267 alone.
我们研究了脂多糖(LPS)的活性成分、合成类脂A(化合物506)及其相关化合物GLA - 60、- 59和- 27对小鼠巨噬细胞激活和细胞因子诱导的影响。无内毒素活性的GLA - 60表现出与LPS或化合物506相当的诱导白细胞介素-1(IL - 1)的活性以及激活小鼠巨噬细胞的能力。本研究考察了GLA - 60与MDP衍生物GMD - 323至- 328的六种缀合物的生物学活性。除GMD - 323外,所有GMD化合物均对IL - 1和杀肿瘤巨噬细胞表现出强效诱导活性,尤其是GMD - 324和- 326,其活性远高于GLA - 60。然而,这些缀合物诱导肿瘤坏死因子(TNF)和集落刺激因子(CSF)的活性低于GLA - 60。MDP衍生物(GMD - 267)与GLA - 60混合物诱导IL - 1的活性高于缀合物(GMD - 324)或单独的GLA - 60和GMD - 267。
