Definitions
- the present invention relates to a novel thiazolopyrimidine derivative having a vasodilator action, an antihypertensive action, a platelet aggregation inhibitory action and a cholesterol lowering action.
- Cardiovascular diseases such as ischemia and cerebral vascular disease, cerebrovascular disease, arteriosclerosis, and hypertension, are a very important disease, as they account for a large proportion of deaths as well as malignant tumors.
- ischemic heart disease, cerebral and peripheral circulatory insufficiency, etc. are caused by insufficient blood flow due to arterial blood and atherosclerosis, resulting in malnutrition at the ischemic site. It is thought to be caused by damage caused by oxygen and lack of oxygen. Therefore, a medicament having an effect of improving blood flow based on vasodilation of an ischemic basin such as a coronary artery is effective for these diseases.
- drugs that suppress platelet aggregation which is one of the causes of arterial thrombosis
- drugs that reduce cholesterol, which induces arteriosclerosis are considered to be useful in preventing the onset of these diseases. Is received.
- OMPI Some have a hypotensive effect, such as larazine, and are commonly used for the treatment of hypotension. Recently, the use of vasodilators in the treatment of heart failure has been attempted, and it has been reported that Ito et al. [Jpn.
- the present inventors believe that the above-mentioned circulatory diseases are mutually related, and that the treatment that comprehensively ameliorates the circulatory disorders is optimal for the treatment.
- 7- getylamino 5-methylthiazolo [5,4-d] pyrimidine has vasodilator, hypotensive, and platelet aggregation.
- the present inventors have found that they have both an inhibitory effect and a cholesterol lowering effect, and have completed the present invention.
- the present invention relates to a pyrimidine derivative comprising 7-getylamino-5-methylthiazolo (54-d) pyrimidine, which can be produced generally as follows. , 4-Jethylamino 6-Melcapto 1-2-Methyl-5-Dinitropyrimidine is reduced according to a known method to convert the 5-position 2-nitro group into an amino group. The aminopyrimidine derivative obtained in this manner is reacted with formic acid to directly close the ring, thereby deriving a thiazo-opened pyrimidine.
- the compound of the present invention obtained in this way can be in the form of a pharmacologically acceptable salt.
- Pharmaceutically acceptable salt forms include, for example, inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid, and maleic acid. Acid addition salts with organic dumplings such as acid, citric acid, tartaric acid, oxalic acid and succinic acid can be produced.
- the compound of the present invention Since the compound of the present invention has a strong vasodilatory action, a hypotensive action, a platelet aggregation a harmful action and a cholesterol lowering action, and is also soluble in water, it can be used as a drug, especially in the circulation. It has excellent properties as a therapeutic agent for organ diseases. Therefore, the compounds of the present invention and the acid addition salts thereof may be used alone or together with other pharmaceutically active compounds in the pharmaceutical industry if desired. It can be converted into products that can be used medically by any of the usual methods together with the mixing agents, fillers, fragrances, etc. it can .
