Besides the electrostatic interactions, especially through hydrogen bond formation, the van der Waals (vdW) interactions with the I19, V27, F98, H100, and L152 residues of CDK6 are also important factors in the binding efficiency of flavonoids against the CDK6/cycD complex. The 3'- and 4'-OH groups on the flavonoid phenyl ring and the 3-OH group on the benzopyranone ring of inhibitor were found to significantly increase the binding and inhibitory efficiency. For all three inhibitors, including both CHS orientations, the conserved interaction between the 4-keto group of the flavonoid and the backbone V101 nitrogen of CDK6 was strongly detected. To understand the flavonoids that inhibit the CDK6/cycD functions, molecular dynamics simulations (MDSs) were performed on three inhibitors, fisetin (FST), apigenin (AGN), and chrysin (CHS), complexed with CDK6/cycD, including the two different binding orientations of CHS: FST-like (CHS_A) and deschloro-flavopiridol-like (CHS_B). The CDK6 complex with cyclin D (CDK6/cycD) drives cellular proliferation by phosphorylation of specific key target proteins. or.cannolaffora fr s A erca s rs tbe 1 drafthg-group fr>plng Qg to argued tbe code co tlons.The cyclin dependent kinases (CDKs), each with their respective regulatory partner cyclin that are involved in the regulation of the cell cycle, apoptosis, and transcription, are potentially interesting targets for cancer therapy. : ut-tbe - ealtborganlratlo lon, gudelnes!ln any y a are unable. courage ge breast feedng-buts crtcs sad a boycott of Nestle Ne: every developng country ( where t to p re p a re tb e fo h n u la property.
