  New 4,4′‐diaminodiphenylsulfone substituted 2,4‐diamino‐5‐benzylpyrimidines were synthesized. These compounds are highly active inhibitors of both bacterial dihydrofolate reductase (DHFR) and dihydropteroic acid synthase (SYN). The simultaneous inhibition of both enzymes leads to autosynergism in whole cells in the same way as known for combinations of sulfonamides with trimethoprim. The inhibitory

  合成了新的4,4'-二氨基二苯砜取代的2,4-二氨基-5-苄基嘧啶。这些化合物是细菌二氢叶酸还原酶 (DHFR) 和二氢蝶酸合酶 (SYN) 的高活性抑制剂。两种酶的同时抑制导致整个细胞中的自协同作用，与已知的磺胺类药物与甲氧苄氨嘧啶的组合相同。抑制活性在来自不同物种（鲁弗分枝杆菌、大肠杆菌、白色念珠菌）的 DHFR 和 SYN 的无细胞系统和分枝杆菌菌株 M. lufu 的全细胞系统中得到证实。这些化合物是在一个分子中结合两种作用机制的罕见例子。

  The invention provides a crosslinkable aromatic resin having a protonic acid group and a crosslinkable group, suitable for electrolytic membranes and binders used in fuel cells, etc., and electrolytic polymer membranes, binders and fuel cells using the resin. The crosslinkable aromatic resin has a crosslinkable group, which is not derived from the protonic acid group and can form a polymer network without any elimination component. This resin exhibits excellent ion conductivity, heat resistance, water resistance, adhesion property and low methanol permeability. Preferably, the crosslinkable group is composed of a C1 to C10 alkyl group directly bonded to the aromatic ring and a carbonyl group, or a carbon-carbon double bond or triple bond. The aromatic resins such as aromatic polyethers, aromatic polyamides, aromatic polyimides, aromatic polyamideimides, aromatic polyazoles, etc., which contain such a crosslinkable group, are preferred as the crosslinkable aromatic resins having a protonic acid group and a crosslinkable group.
