The present invention provides a crystalline salt of chlorhexidine chloride having a spherical morphology under Scanning Electron Microscopy (SEM) comprising a chloride anion and a cation selected from the group consisting of calcium, sodium, potassium, magnesium, zinc, strontium or iron, processes for the preparation of the salt, compositions, pharmaceutical compositions and uses thereof in medicine. Also provided are crystalline forms of the salt and fibres comprising the same.

The present invention belongs to the field of pharmaceutical synthesis, disclosing a synthetic process and application of metformin hydrochloride, which is to take dicyandiamine and dimethylamine, after dissolving in lower alcohol, adding sodium alkoxide, mixing evenly and gradually raising the temperature for condensation reaction, after the reaction ends, adding hydrochloric acid to adjust the pH to acidic, that is, metformin hydrochloride as described. The synthetic process of metformin hydrochloride provided in this invention, reduces the energy consumption during the reaction, reduces the production cost, and reduces the difficulty of product purification. The present invention is applicable to the synthesis of metformin hydrochloride, the as synthesized metformin hydrochloride is used to prepare metformin hydrochloride sustained release tablets.

The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.

The present invention provides the use of a metformin salt, particularly metformin monothreonate, in the preparation of a medicament for treating cerebral infarction. The metaformin monothreonate of the present invention has an excellent effect in the treatment of cerebral infarction. The present invention also provides a method for preparing metformin monothreonate and a composition comprising metformin monothreonate.

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.
