Abstract: The embodiment of the invention provides a method, apparatus, device and storage medium for generating ligand molecules. The method comprises: determining a set of initial arms by decomposing a reference ligand molecule for a target biological target; generating a set of candidate ligand molecules based on the set of initial arms; determining a set of candidate arms corresponding to each of the set of initial arms by decomposing each of the set of candidate ligand molecules; determining a target candidate arm for each initial arm from the set of candidate arms to determine a set of target candidate arms; and generating a set of ligand molecules for the target biological target based on the set of target candidate arms. In this way, by selecting the key information (i.e., the arm) more fitting the drug design target in the drug design process as a condition, the embodiments of the present disclosure can improve the ratio of the candidate drug molecules to the drug design target.

Abstract: A biological polypeptide applied to inhibition of intracellular lipid accumulation and a synthesis method thereof are provided. An amino acid sequence of the polypeptide is shown in SEQ ID NO: 1 in sequence listing. The polypeptide has relatively high target affinity and high activity, and can exhibit remarkably high activity at extremely low dosages and concentrations. The polypeptide inhibits binding of clusterin and sterol O-acyltransferase by exerting competition on the clusterin to reduce the activity of the sterol O-acyltransferase, so as to achieve functions of controlling physiological metabolism in organisms, such as relieving lipid accumulation in hepatocytes, resisting tumor occurrence, assisting anti-cancer drugs in inhibiting tumor growth, and the like.

Abstract: The present invention relates to the detection of promoter methylation status using a combination of either modification of methylated DNA or restriction endonuclease digestion, multiplex polymerase chain reaction, ligase detection reaction, and a universal array or capillary electrophoresis detection.
