  The present invention describes novel 2,4-­disubstituted 1,3-dioxolanes having the formula I wherein R¹ represents a long chain alkyl group; X is a covalent single bond, a carbonyl group, a carboxyl group, a carbamoyl group or a -O-P(=0)(Oz)- group; z is a negative charge (-) when q is zero, or z is an hydrogen atom when q is one; n is an integer from 2 to 10; R², R³ and R⁴ are lower alkyl groups, or R²R³R⁴N⁺ represents an aromatic cyclic ammonium group or R²R³R⁴N⁺ represents a non-aromatic cyclic ammonium group in which two of the groups (R², R³ or R⁴) form a non-aromatic ring together with the quaternary nitrogen atom; and A⁻ is a pharmaceutically acceptable anion. These compounds are in vitro inhibitors of the platelet aggregation induced by the platelet activating factor (PAF) and, thus, useful for the treatment of the diseases in which this substance is involved. On the other hand, some of these compounds have hypotensive activity without provoking activation of the platelets.

  本发明描述了新型 2,4-二取代 1,3-二氧戊环，其式为 I 其中 R¹ 代表长链烷基；X 为共价单键、羰基、羧基、氨基甲酰基或 -O-P(=0)(Oz)- 基团；当 q 为零时，z 为负电荷 (-)，或当 q 为一时，z 为氢原子；n 为 2 至 10 的整数；R²、R³和 R⁴ 是低级烷基，或 R²R³R⁴N⁺ 代表芳香族环状铵基，或 R²R³R⁴N⁺ 代表非芳香族环状铵基，其中两个基团（R²、R³或 R⁴）与季氮原子一起形成非芳香族环；以及 A- 是药学上可接受的阴离子。这些化合物是血小板活化因子（PAF）诱导的血小板聚集的体外抑制剂，因此可用于治疗与该物质有关的疾病。另一方面，其中一些化合物具有降血压活性，但不会引起血小板活化。

  The present invention addresses the problem of providing an electroconductive composition which, even when burned in the air, can form an electroconductive film that exhibits satisfactory electroconductivity and moist-heat resistance. The problem is solved with an electroconductive composition which comprises: a surface-treated copper powder (AB) comprising a copper powder (A) and an ascorbic acid derivative (B) adherent to the surface thereof; a binder resin (C); and a dispersant (D) having an acidic group.
