Abstract

The invention belongs to the field of medical and chemical industry, relates to indoline diketopiperazine spiro-compounds as well as a preparation method and use thereof, and in particular relates to compounds as shown in formula I or pharmaceutically acceptable salts of the compounds. The compounds have a framework dimerization molecular structure condensed by terracycloindoline diketopiperazine and 1-oxa spiro[4, 5] decane. Two ethylene oxide structures are arranged on the spiro hexatomic ring. The invention further relates to penicillium purpurogenum for preparing the compounds as shown in the formula I. Experiments show that the compounds can be used for preparing cytoskeletal protein inhibitors, apoptosis inducers, tumor cell proliferation inhibitors, tumor cell killing agents or antitumor drugs. The compounds provided by the invention have good antitumor activity.

Description

technical field [0001] The invention belongs to the field of medicine and chemical industry, and relates to a class of spiro compounds, in particular to indoline diketopiperazine spiro compounds, and the invention also relates to a composition comprising the indoline diketopiperazine spiro compounds, And the preparation method and application of indoline diketopiperazine spiro compound. Background technique [0002] Tumor is a new organism formed by the body under the action of various carcinogenic factors, a certain cell in the local tissue loses its normal regulation of its growth at the gene level, resulting in abnormal clonal proliferation. Tumors are generally divided into benign and malignant. All malignant tumors are collectively called cancer. [0003] The structure types of spiro compounds are very rich. Only spiro[4,5]decane compounds can form many different structural types because one or more of different positions on the spiro ring skeleton are replaced by he...
