Interaction of some asymmetrical porphyrins with u937 cell membranes-in vitro and in silico studies

HIGHLIGHTS

SUMMARY

    Positive controls were docked into the binding_sites of SERCA2b, Slo1, and the SUR2 subunit of KATP, as a means to validate the docking procedure. One carboxyl moiety was also involved in hydrogen_bonding with Thr744 and formed a carbon hydrogen_bond with Glu742. The studied asymmetric porphyrin derivatives were docked on a binding pocket of SERCA2b that overlaps with the BHQ binding_site. The docking results indicate that both the free base porphyrin derivative and its corresponding metalloporphyrins have the potential to inhibit SERCA2b by interacting with the same binding_site. The same observation could be made for . . .
