Abstract: The coating formation method of the present invention is a method for forming a coating on a surface of a coating formation target. The formation method of the present invention includes an electrostatic spraying step of electrostatically spraying a composition directly onto the coating formation target, thereby forming a coating composed of a deposit containing fibers. The composition contains a component (a), a component (b), and a component (c) below. (a) One or more volatile substances selected from water, alcohols, and ketones. (b) A polymer having coating formability. (c) A liquid agent containing one or more selected from oils and polyols that are in a liquid form at 20° C.
Abstract: The present invention provides a multi-drug-loading site and high drug-loading capacity ligand-drug conjugate. The ligand-drug conjugate has a structure of general formula (I). The ligand-drug conjugate has the characteristics of high loading capacity, high drug efficacy, low toxicity, and low risks. The ligand-drug conjugate can be used particularly to connect to a low toxicity chemical molecule, thereby extending a therapeutic window. Furthermore, the present invention provides an antibody-drug conjugate molecule. The antibody-drug conjugate molecule has the characteristics of multiple drug-loading ability and high drug-loading capacity, such that the antibody-drug conjugate can carry a large amount of a low toxicity chemical molecule and achieve a therapeutic effect without depending on antibody targeting or high toxicity chemicals.
