5results about How to "Reduce hydrophobicity" patented technology

This invention belongs to the field of material performance testing technology, specifically relating to a method for determining the particle density of carbon anode raw materials. The method includes: injecting water into a first container until the liquid levels in the first and second containers are equal, and reading the scale of the first and second containers as V1; adding carbon anode raw material particles with a mass of m, including petroleum coke or calcined coke, into the first container; injecting a mixed solution into the first container until the carbon anode raw material particles are completely submerged, the mixed solution including pure water and a low-foaming nonionic surfactant; pre-treating the first and second containers in an ultrasonic instrument; and placing the pre-treated first and second containers into a vacuum chamber, evacuating the chamber until it reaches negative pressure, and maintaining the pressure in the vacuum chamber. This method for determining the particle density of carbon anode raw materials can accurately measure the particle density of carbon anode raw materials.

This invention relates to the pharmaceutical field, specifically to linker drug conjugates, antibody drug conjugates, their preparation methods, and applications. Specifically, this invention relates to a linker drug conjugate, or a pharmaceutically acceptable salt, solvate, or solvate of said salt thereof, wherein the linker drug conjugate has the structure shown in Formula I, wherein M is a chemical structure containing a maleimide (m) fragment or a cyclooctyne fragment, X is a linker fragment consisting of 1-5 amino acids or their derivatives, and D is a cytotoxic agent. The linker drug conjugate of this invention can release the payload through enzymatic hydrolysis after removing the hydrophobic PAB structure, thereby reducing the hydrophobicity of the linker-drug and decreasing the polymer content generated during ADC preparation, while also exhibiting corresponding cytotoxic activity, M-X-D Formula I.
