The present invention provides a compound having a specific chemical structure and having PDE9A inhibitory activity, or a pharmaceutically acceptable salt thereof. The present invention provides a composition containing the compound or a pharmaceutically acceptable salt thereof. The present invention provides a pharmaceutical use, for treating or preventing PDE9A-related diseases, of the compound according to the present invention, a salt thereof, and a composition containing the compound or salt. The present invention also provides a method for treating or preventing PDE9A-related diseases, the method comprising administering an effective amount of the compound according to the present invention, a salt thereof, or a composition containing the compound or salt to a subject in need of treatment.

Compounds having PDE9A inhibitory activity, and pharmaceutical uses thereof

The present invention relates to a pharmaceutical composition for preventing or treating tuberculosis, comprising: (a) a pharmaceutically effective amount of a compound represented by the following chemical formula 1; and (b) a pharmaceutically acceptable carrier. Chemical formula 1 The compound contained as an active ingredient of the present invention inhibits the expression and activity of CO-DH in tubercleso as to effectively block the detoxification of carbon monoxide, which is an important survival factor of tubercle, and is safe for the human body since the compound targets CO-DH which does not exist in the human body. In addition, the compound creates a synergistic effect when combined with a conventional tuberculostatic drug, and thus can be more effective for treating tuberculosis.

Pharmaceutical composition for preventing or treating tuberculosis

A pharmaceutical composition comprising a phenyltetrazole derivative of formula (I) or a pharmaceutical acceptable salt thereof is effective in preventing or treating osteoporosis, obesity, diabetes, or hyperlipidemia, by regulating protein TAZ.  wherein, A is ethyl or n-butyl; Ris methyl, &#x2014;CHOH, &#x2014;COCH, &#x2014;CHF, &#x2014;CH(OCH), &#x2014;CHOC(&#x2550;O)CH, styryl or &#x2014;CHOCHSCH; Ris H, Br, &#x2014;COCH, phenyl, pyridin-2-yl, pyridin-3-yl, or styryl; Ris H or methyl; X is CH or N; and P is H or &#x2014;CH(CH)OCHCH.

Pharmaceutical composition for preventing or treating osteoporosis or obesity comprising phenyltetrazole derivative

A phamaceutical composition comprising a phenyltetrazole derivative of formula (I) or a pharmaceutical acceptable salt thereof is effective in preventing or treating osteoporosis, obesity, diabetes, or hyperlipidemia, by regulating protein TAZ.  

The present invention is directed to a novel imidazole derivative having an aryl piperidine substituent of formula (I) and a method for preparation thereof, and a pharmaceutical composition containing said imidazole derivative as an active ingredient for preventing or treating a MCH (melanine-concentrating hormone)-related disease.

Imidazole derivatives having aryl piperidine substituent, method for preparation thereof and pharmaceutical compositions containing same

The present invention is related to benzothiophen-2-carbonylguanidine derivatives, a preparation method thereof, and pharmaceutical compositions containing the same. The derivatives have potent inhibitory effect on the sodium/hydrogen exchanger NHE-I, improve the functional recovery of ischemia/reperfusion-induced heart injury in isolated ischemic heart models, and significantly reduce the myocardiac infarct size in in vivo ischemic animal models, thereby showing excellent cardioprotective effects. Also, the derivatives are protective of both neuronal cells and the brain as proven by their protective effects on neuronal cells from necrosis and apoptosis and by their ability to significantly reduce cerebral infarct sizes in in vivo ischemic brain models. The derivatives can be effectively used for the prevention and treatment of ischemic heart diseases such as myocardiac infarction, arrhythmia, angina pectoris and the like, and cerebrovascular diseases such as cerebral stroke and be used as cardioprotective agents to the patients undergoing reperfusion therapy including chemicals such as thrombolytic agents, or surgery such as coronary artery bypass and percutaneous transluminal coronary angioplasty.

Benzothiophen-2-carbonylguanidine derivatives, preparation thereof, and pharmaceutical composition containing the same

Provided are aminopyrazole derivatives, a process for the preparation thereof, and a composition for preventing or treating an ischemic disease containing the same. Since the aminopyrazole derivatives of the present invention can reduce an ischemic cell death significantly, they can be effectively used for the prevention and treatment of ischemic diseases mediated by ischemic cell death, or protection of organs.

Aminopyrazole derivatives, process for the preparation thereof, and composition for preventing or treating ischemic diseases containing the same

The present invention relates to benzopyran derivatives substituted with a thioxobenzoxazole derivative, or pharmaceutically acceptable salts thereof, processes for preparing the same and a pharmaceutical composition containing the above as an effective ingredient Benzopyran derivatives substituted with thioxobenzoxazole derivatives, represented in &#x3c;Formula 1&#x3e;, have the function of protecting heart from ischemia-reperfusion both in vivo and in vitro, so that a pharmaceutical composition containing benzopyran derivatives substituted with thioxobenzoxoazole derivatives or pharmaceutically acceptable salts thereof of the present invention as an effective ingredient can be effectively used for the protection of tissues influenced by ischemia-reperfusion, for example, for the protection of heart, nervous cells, brain, retinal cells, storage organs, etc, and for the treatment of diseases caused by ischemia-reperfusion.

Benzopyran derivatives substituted with a thioxobenzoxazole derivative, pharmaceutically acceptable salts thereof, their preparations and pharmaceutical compositions containing them

The present invention relates to furancarbonylguanidine derivatives, a preparation method thereof and a pharmaceutical composition comprising the same. Furancarbonylguanidine derivatives of the present invention inhibit NHE-1 (sodium-hydrogen exchanger isoform 1), which helps recovery of heart function damaged from ischemia/reperfusion and decreases myocardial infarction rate, indicating that they have protective effect on myocardial cells. Thus, furancarbonylguanidine derivatives of the present invention can be effectively used for the prevention and the treatment of ischemic heart diseases such as myocardial infarction, arrhythmia, angina pectoris, etc, and also a promising candidate for a heart protecting agent applied to reperfusion therapy including thrombolytics or cardiac surgery including coronary artery bypass graft, percutaneous transluminal coronary angioplasty, etc.
