Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] refer to figure 1 , The implementation steps of this example are as follows:
[0042] Step 1, download the drug data and construct five drug similarity networks.
[0043] 1a) Taking the DrugBank database as an example, build a drug chemical structure similarity network N ch :
[0044] 1a1) Download the chemical structure data CH of 1284 drugs from the DrugBank database 1284 ;
[0045] 1a2) Based on the chemical structure data CH of the drug 1284 , use the PaDEL-Descriptor software to get the chemical structure feature set of the drug The collection has 1284 medicinal chemical structure features;
[0046] 1a3) Based on the collection of medicinal chemical structure features Get medicinal chemical structure similarity network N ch , any element in the network is calculated as follows:
[0047]
[0048] Among them, ...
