    • The present invention relates to cis- and trans-forms of pyrazole derivatives, salts thereof, or agents containing the same, and represented by the general formula (I): wherein G represents a nitrogen containing saturated heterocyclic structure represented by the following formula: These compounds exhibit anti-tumor activity on 5-FU-resistant tumors and effects on P glycoprotein expressing, multiple-drug resistant tumors. An example of a pyrazole derivative which demonstrates 50% inhibition of tumor cell growth is 3-[4-(3-chloro-5-fluorophenyl)-1 piperazinyl]-1-[1-(3-chloro-2-pyridyl)-5-methyl-4-pyrazolyl)-1-trans-propene hydrochloride. Synthesis of the compounds represented by formula (I) can be prepared by any one of various routes such as a Mannich reaction, a Wittig reaction, reductive amination or substitution by allylation.
    • 本发明涉及吡唑衍生物,其盐或含有该取代基的吡唑衍生物,其盐或其代表物的顺式和反式,其通式(I)表示:其中G表示由下式表示的含氮饱和杂环结构:这些 化合物对5-FU抗性肿瘤表现出抗肿瘤活性,对P糖蛋白表达,多重耐药性肿瘤有影响。 显示50%抑制肿瘤细胞生长的吡唑衍生物的实例是3- [4-(3-氯-5-氟苯基)-1-哌嗪基] -1- [1-(3-氯-2-吡啶基) - 5-甲基-4-吡唑基)-1-反丙烯盐酸盐。 由式(I)表示的化合物的合成可以通过各种途径中的任何一种制备,例如曼尼希反应,维蒂希反应,还原胺化或烯丙基取代。
