Kaspaz-1 için peptit bazlı ilaç tasarımı ve metabolik yol analizi

As one of the mostly studied protein in the literature, caspase-1 (ICE) attracts the attention of many scientists due to its crucial roles in inflammatory responses. It has other roles in the apoptotic path, for example, because of having more than 40 substrates. Increased expression of its substrates such as pro-IL-1beta results in inflammatory disorders. Consequently, inhibition and pathway studies related to caspase-1 have gained importance.Peptide based drug design for caspase-1 is performed and potent inhibitors are determined computationally. Bicylic (a molecule that contains two fused rings) and ketone structures with Asp and D-enantiomeric aminoacids are obtained as good inhibitors in accordance with previous experimental work. Moreover, multi-target drug determination in the caspase-1 pathway is made. Conformational factors in tripeptides are also taken into consideration with Viterbi Algorithm, which indicates whether a peptide can change its conformation from minimized state to bound state.Knockout analysis on the ICE pathway by Gaussian Network Model (GNM) shows knockouts of NLRP3, ASC, caspase-1, NF-kappaB, pro-IL-33, TLR4, TLR2, TRIF and MyD88 are effective.?
