This invention refers to a process to obtain new mixed copper aminoacidates from phenanthrolines and their alkyl derivates of an aromatic type to be used as anticancerigenic, agents preferably with a therapeutic use for the treatment of liquid and solid cancerigenic tumours such as leukemia. The complexes obtained are of the [Cu (N-N) (N-O)]⁺⁻ NO₃ type in which the N-N ligand corresponds to 4, 7-dimethyl-1, 10 phenanthroline and the N-O ligand preferably correponds to one of the aminoacidates such as tyrosine-alaninate, treoninate, triptophanate, valinate, isoleucinate, cisteinate, diglycinate, phenylalaninate, glycinate, hystidinate, serinate, tyrosinate, aspartate, alaninate and phenylalaninate. The process is characterized because it includes the following steps: making an aqueous solution based on an aliphatic alcohol and 4, 7-dimethyl-1, 10 phenanthroline react with a copper complex preferably CuNO₃5H₂O at room temperature, and immediately after making the obtained product react in an aqueous aminoacidate solution adjusting a slightly alkaline pH.
本发明涉及一种从菲罗啉及其芳香族烷基衍生物中获得新的混合氨基酸铜的工艺,该工艺可用作抗癌剂,优选用于治疗液态和固态致癌肿瘤,如白血病。所获得的配合物为[Cu (N-N) (N-O)]⁺- NO₃型,其中 N-N 配体对应于 4,7-二甲基-1,10-菲罗啉,N-O 配体最好对应于氨基酸盐之一,如酪氨酸丙氨酸盐、曲安酸盐、三色氨酸盐、氨酸、三色氨酸、缬氨酸、异亮氨酸、肌氨酸、二甘氨酸、苯丙氨酸、甘氨酸、胱氨酸、丝氨酸、酪氨酸、天门冬氨酸、丙氨酸和苯丙氨酸。该工艺的特点是包括以下步骤:在室温下,使基于脂肪醇和 4,7-二甲基-1,10-菲罗啉的水溶液与铜络合物(最好是 CuNO₃5H₂O)反应,然后立即使得到的产物在调节 pH 值为微碱性的氨基酸水溶液中反应。
