The present invention relates to a guanidine compound and a use thereof, and more specifically, to a guanidine derivative showing excellent effects of inhibiting cancer cell proliferation, cancer metastasis, and cancer recurrence; a preparation method thereof; and a pharmaceutical composition containing the same as an active ingredient. Compared to existing drugs, the guanidine derivative according to the present invention shows excellent effects of inhibiting cancer cell proliferation, cancer metastasis, and cancer recurrence even with small doses, and may thus be effectively used in preventing or treating various cancers such as uterine cancer, breast cancer, stomach cancer, brain cancer, rectal cancer, colorectal cancer, lung cancer, skin cancer, blood cancer, liver cancer, etc., inhibiting cancer cell proliferation and cancer metastasis.

Biguanide compound and use thereof

The present invention relates to guanidine compounds for inhibiting mitochondrial oxidative phosphorylation (OXPHOS) and use thereof. More specifically, the present invention relates to a pharmaceutical composition for preventing or treating a OXPHOS-related disease, particularly cancer, by inhibiting mitochondrial oxidative phosphorylation and reprogramming cellular metabolism.

Guanidine compounds and use thereof

The present invention relates to guanidine compounds for inhibiting mitochondrial oxidative phosphorylation (OXPHOS) and use thereof. More specifically, the present invention relates to a pharmaceutical composition for preventing or treating a OXPHOS-related disease, particularly cancer by inhibiting mitochondrial oxidative phosphorylation and reprogramming cellular metabolism.

The present invention provides an N1-cyclic amine-N5-substituted biguanide derivative compound represented by Formula 1, a method of preparing the same and a pharmaceutical composition including the biguanide derivative or the pharmaceutically acceptable salt thereof as an active ingredient. The biguanide derivatives have an effect of inhibiting cancer cell proliferation, cancer metastasis and cancer recurrence by activation of AMPK, even when administered in a small dose compared with conventional drugs.

N1-cyclic amine-N5-substituted biguanide derivatives, methods of preparing the same and pharmaceutical composition comprising the same

The present invention relates to biguanide compounds and use thereof, more particularly, to biguanide derivatives exhibiting excellent effects for inhibition of cancer cell proliferation and inhibition of cancer metastasis and recurrence, a method for preparing the same, a pharmaceutical composition containing the same as an active ingredient, and a method of prevention or treatment of cancer comprising the step of administering an effective amount of the composition to a subject in need thereof.

Biguanide compounds and use thereof

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.

Pharmaceutical composition comprising N1-cyclic amine-N5-substituted biguanide derivatives as an ingredient for preventing or treating fibrosis

The present invention relates to novel cephalosporin derivatives represented by X, Y, L, R1, and R2 are as same as defined in the description of the invention. The present invention also relates to pharmaceutical antibiotic compositions comprising a novel celphalosporin derivative represented by Chemical Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient. According to the present invention, novel cephalosporin derivatives, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient for the broad spectrum of antibiotic resistant, low toxicity, particularly in Gram-negative bacteria, which can be useful with strong antimicrobial activity.

Cephalosporin derivatives and pharmaceutical compositions thereof

Disclosed is a novel oxazolidinone derivative represented by Formula 1 above, in particular, a novel oxazolidinone compound having a cyclic amidoxime or cyclic amidrazone group. In Formula 1, R and Q are the same as defined in the detailed description. In addition, disclosed is a pharmaceutical composition for an antibiotic which includes the novel oxazolidinone derivative of Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The novel oxazolidinone derivative, the prodrug thereof, the hydrate thereof, the solvate thereof, the isomer thereof, and the pharmaceutically acceptable salt thereof have broad antibacterial spectrum against resistant bacteria, low toxicity and strong antibacterial effects against Gram-positive and Gram-negative bacteria and thus may be effectively used as antibiotics.
