I have. Microtubules are tubular protein fibers with a diameter of about 25 nm, which are widely found in eukaryotic cells such as animals and plant fungi, and are destroyed by polymerization and depolymerization in the cell cycle. The formation of the mitotic apparatus, the formation and maintenance of cell morphology, flagella and ciliary motility, substance transport in neurons and pigment cells, hormone secretion, and fluidity of cell membranes are extremely diverse. Compounds that act on this microtubule system and bind to tubulin to inhibit tubulin polymerization show various biological activities such as cell division inhibition, and include anticancer drugs, antifungal agents, anthelmintics, herbicides A wide range of effects are expected. On the other hand, angiogenesis is mainly the formation of new vascular networks by vascular endothelial cells in venules. This angiogenesis involves the process of solid tumor development, wound healing, inflammation, and intrauterine It has been observed in many diseases, such as meningiosis, rheumatoid arthritis, diabetic retinopathy, ischemic heart disease, arteriosclerosis, and psoriasis vulgaris. In these diseases, various angiogenic factors that induce angiogenesis work in a complex manner to form a new vascular network, which proliferates cells involved in various diseases, including tumor growth and metastasis. It is thought to be one of the causes of worsening the symptoms. Therefore, compounds that can effectively inhibit angiogenesis found in these diseases are useful as preventive or therapeutic agents for malignant tumors, endometriosis, rheumatoid arthritis, diabetic retinopathy, arterial sclerosis, etc. A wide range of effects is expected.
また、 p 5 3蛋白は、 癌抑制遺伝子である p 5 3遺伝子により発現さ れる 3 9 3個のアミノ酸から構成される蛋白質であり、 D N Aの完全な 状態を保持することを特別の役目としている。 この P 5 3蛋白は正常な 身体の細胞にはほとんど見られないが、 D N Aに障害が起こると、 細胞 の P 5 3蛋白のレベルが上昇し、 まず、 細胞周期を G 1期に止め、 D N A複製を行う S期への進行を阻止し、 この間に D N Aの修復を行わせる 力、、 あるいはその細胞をアポトーシスに導くように作用する。 しかし、 P 5 3蛋白は、 通常はかなり大きな分子分解速度を有する代謝回転が速 い蛋白質であり、 D N Aの障害により起こる細胞の癌化の過程で産生さ れた P 5 3蛋白は、 多くの癌細胞には効果のない変異型の p 5 3蛋白が 大量に含まれているという事実が示すように、 容易に変異を受け不活性 化されやすいのである。 このように p 5 3蛋白が欠損又は不活性化され ることにより、 発癌性の変異を受けた細胞の増殖が阻止されなくなり、 また、 そのような細胞が***してさらに発癌性の変異が作られるのを許 すこととなる。 従って、 p 5 3蛋白の安定化作用を示す化合物は、 D N A障害の修復を効果的に促進することができ、 D N Aの障害により生じ る疾病、 例えば癌等の予防又は処置のために、 単独であるいは P 5 3遺 伝子治療における補助剤としての用途が期待される。 The p53 protein is a protein composed of 393 amino acids expressed by the p53 gene, which is a tumor suppressor gene, and has a special role to maintain the integrity of DNA. . This P53 protein is rarely found in normal body cells, but when DNA damage occurs, the level of P53 protein in the cells rises. It blocks the progression to the replicating S phase, during which it repairs DNA, or acts to lead the cell to apoptosis. However, the P53 protein is a protein with a high rate of turnover that usually has a considerably high molecular degradation rate, and the P53 protein produced in the process of canceration of cells caused by DNA damage is Cancer cells are easily mutated and inactivated, as evidenced by the fact that cancer cells contain large amounts of ineffective mutant p53 protein. Deletion or inactivation of the p53 protein in this way prevents the growth of cells with oncogenic mutations from being blocked, It would also allow such cells to divide and make more oncogenic mutations. Therefore, a compound exhibiting a p53 protein stabilizing effect can effectively promote the repair of DNA damage, and can be used alone for the prevention or treatment of diseases caused by DNA damage, such as cancer. Alternatively, it is expected to be used as an adjunct in P53 gene therapy.

Med. Chem. Vol. 38, 2041-2049). (1995)), exhibiting angiogenesis inhibitory activity (Cancer Research, Vol. 57, 81-86 (1997)), and exhibiting a stabilizing effect on p53 protein (Oncogene, Vo 1.14). 379-384 (1997)), but this compound has the disadvantage of being susceptible to metabolic inactivation.
今回、 ステロイ ドの D環部に酸素原子が導入された前記式 ( I ) で示 される新規な 2—置換— D—ホモォキサステロイ ド誘導体が、 優れたチュ 一プリ ン重合阻害作用、 血管新生阻害作用及びノ又は p 5 3蛋白の安定 化作用を示し、 しかも代謝不活性化を受けにくいことが見出された。  This time, a novel 2-substituted-D-homoxosteroid derivative represented by the above formula (I) in which an oxygen atom has been introduced into the D ring portion of steroid has an excellent inhibitory action on tuupulin polymerization, It has been found that the compound has an angiogenesis inhibitory effect and a stabilizing effect on the NO or p53 protein and is less susceptible to metabolic inactivation.
