Abstract: The present invention provides a novel use of N1-cyclic amine-N5-substituted biguanide derivatives for preparing a medicine for preventing or treating fibrosis. The N1-cyclic amine-N5-substituted biguanide derivatives according to the present invention are capable of effectively inhibiting fibrosis by effectively suppressing the EMT.

Abstract: The present invention provides novel uses of a biguanide derivative for preventing or treating glioblastoma. The compound of Formula 1 and its pharmaceutically acceptable salts can be used for preventing and treating glioblastoma. Further, the combined treatment of the compound of Formula 1 and temozolomide can provide superior effects compared to the administration of the compound of Formula 1 alone or temozolomide alone.

Abstract: A pharmaceutical composition comprising losartan or a pharmaceutically acceptable salt thereof, which is capable of treating or preventing side effects such as muscle toxicity caused by administering a statin-based lipid-lowering drug, and a pharmaceutical combination composition comprising a statin drug and a losartan drug as active ingredients are provided. The pharmaceutical composition comprising losartan or a pharmaceutically acceptable salt thereof provides an effect on treating or preventing muscle-related side effects caused by administration of a statin drug for treating hyperlipidemia, as well as an intrinsic pharmacological effect for treating or preventing hypertension. When administered along with a statin drug in sequence or co-administered at the same time with the statin drug, the pharmaceutical composition can exhibit an effect of effectively or significantly decreasing or preventing side effects such as muscle toxicity.
