Four new salicylaldehyde derivatives with a glucose or mannose moiety were synthesized with 2-tert-butylphenol or 4-tert-butylphenol as the starting material, followed by the formylation, chloromethylation, nucleophilic substitution reaction with the desired carbohydrate. The salicylaldehyde derivatives condensed with ethylenediamine to give the Schiff bases, which coordinated with Mn to afford four novel sugar-based Salen Mn complexes.

首先，分别以2-叔丁基苯酚和4-叔丁基苯酚为起始原料，经过甲酰化反应、氯甲基化反应、和糖类衍生物的亲核取代反应制得了四种新型并入葡萄糖基或甘露糖基的水杨醛衍生物，将它们与乙二胺缩合生成希夫碱配体，得到的配体与过渡金属Mn~(3+)配位制备出四种新型含糖基的Salen Mn配合物。

从土壤及霉变淀粉质材料等样品中分离获得到产糖化酶活性较高的菌株L-3，经鉴定为一种紫红曲霉；通过紫外线和硫酸二乙酯分别进行诱变，得到4株性能良好的糖化酶变异株，其中菌株7性能最好，命名为M.F7。

Ethambutol is a first-line drug used for antituberculosis therapy. It is often used in combination with isoniazid, rifampin, pyrazinamide, and streptomycin. The action of EMB in antituberculosis mechanism is the destruction of cell wall of tubercle bacilli via binding the target molecule -- arabinosyl transferases. These enzymes are involved in the polymerization of the cell wall arabinan. Inhibition of arabinan synthesis by EMB results in the accumulation of mycolic acids, leading to cell death.The EMB-resistance of MTB is involved with the mutation of emb operon or the over expression of emb operon.

乙胺丁醇是和异烟肼、利福平、链霉素、吡嗪酰胺联合治疗结核病的一线抗结核药物，EMB对结核分枝杆菌的作用机制与分枝杆菌胞壁结构破坏有关，主要作用于靶分子阿拉伯糖基转移酶，抑制了阿拉伯糖基聚合入阿拉伯半乳聚糖，从而影响细胞壁分枝菌酸-阿拉伯半乳聚糖-肽聚糖复合物的形成，导致菌细胞的死亡。
