Homo sapiens 122-147 16853517-1 2005 The photophysics of hypericin have been studied in its complex with two different isoforms, A1-1 and P1-1, of the protein glutathione S-transferase (GST). hypericin 20-29 glutathione S-transferase kappa 1 Homo sapiens 149-152 15947580-1 2005 PURPOSE: We investigated the importance of E-cadherin expression on the selective accumulation of hypericin in superficial bladder cancer after intravesical instillation. hypericin 98-107 cadherin 1 Homo sapiens 43-53 15947580-7 2005 Taken together the data point to an inverse relationship between E-cadherin

hypericin bound to GST A1-1, binding to GST P1-1 suppresses singlet oxygen generation to almost negligible levels. hypericin 76-85 glutathione S-transferase alpha 1 Homo sapiens 95-103 16853517-10 2005 The data are rationalized in terms of a simple model in which the hypericin photophysics depends entirely upon the decay of the triplet state by two competing processes, quenching by oxygen to

studies, we analyzed the dynamic changes in Ca2+ influx and free intracellular Ca2+ concentration ([Ca2+]i) of cultured human retinal pigment epithelial (RPE) cells after stimulation with hypericin in an attempt to elucidate its mechanism as a therapeutic drug for PVR. hypericin 203-212 carbonic anhydrase 2 Homo sapiens 94-97 15821349-7 2005 In contrast, stimulation with higher concentrations of hypericin (1-5 microM) led to a rapid decrease in Ca2+ influx and [Ca2+]i, which was significantly different from those detected without hypericin (control experiments). hypericin 55-64 carbonic anhydrase 2 Homo sapiens 105-108 15821349-7 2005 In contrast, stimulation with higher concentrations of hypericin (1-5 microM) led to a rapid decrease in Ca2+ influx and [Ca2+]i, which was

inhibit human cytochrome P450 (CYP) enzyme activities; however, its potential interactions that inhibit human carboxylesterases 2 (hCE2) were unclear. hypericin 33-42 carboxylesterase 2 Homo sapiens 187-191 35114918-3 2022 PURPOSE: The study aimed to investigate the inhibition of hypericin on hCE2. hypericin 58-67 carboxylesterase 2 Homo sapiens 71-75 35114918-4 2022 METHODS: The inhibition of hypericin on hCE2 was studied by using N-(2-butyl-1,3-dioxo-2,3-dihydro-1H-phenalen-6-yl)-2-chloroacetamide (NCEN). hypericin 27-36 carboxylesterase 2 Homo sapiens 40-44 35114918-5 2022 The type of inhibition of hypericin on hCE2 and the corresponding inhibition constant (Ki) value were determined. hypericin 26-35 carboxylesterase 2 Homo sapiens 39-43 35114918-6 2022 The inhibition of hypericin on hCE2 in living cells was discussed. hypericin 18-27 carboxylesterase 2 Homo sapiens 31-35 35114918-7 2022 The herb-drug interactions (HDI) risk of hypericin and hCE2 in vivo was predicted by estimating the drug concentration-time curve (AUC) ratio of hypericin and hypericin free. hypericin 145-154 carboxylesterase 2 Homo sapiens 55-59 35114918-7 2022 The herb-drug interactions (HDI) risk of hypericin and hCE2 in vivo was predicted by estimating the drug concentration-time curve (AUC) ratio of hypericin and hypericin free. hypericin 159-168 carboxylesterase 2 Homo sapiens 55-59 35114918-8 2022 To understand the inhibition mechanism of hypericin on the activity of hCE2 in-depth, molecular docking was performed. hypericin 42-51 carboxylesterase 2 Homo sapiens 71-75 35114918-12 2022 Moreover, hypericin distinctly suppressed hCE2 activity in living cells. hypericin 10-19 carboxylesterase 2 Homo sapiens 42-46 35114918-13 2022 In addition, the AUC of hCE2 metabolic drugs with metabolic sites similar to NCEN was estimated to increase by up to 5%, in the presence of hypericin. hypericin 140-149 carboxylesterase 2 Homo sapiens 24-28 35114918-15 2022 Further, molecular simulations indicated that hypericin could strongly interact with ASP98, PHE307, and ARG355 to form four hydrogen bonds within hCE2. hypericin 46-55 carboxylesterase 2 Homo sapiens 146-150 35114918-16 2022 CONCLUSION: These findings are of considerable clinical significance to the combination of hypericin-containing herbs and drugs metabolized by hCE2. hypericin 91-100 carboxylesterase 2 Homo sapiens 143-147
