Droxidopa 88-92 ATP binding cassette subfamily B member 1 Homo sapiens 176-182 21104228-10 2011 Stratified analyses revealed that in the high weight group in AROS individuals homozygous for the variant allele had a decreased BMD (p <= 0.02), whereas the same pattern was found in the low weight group in DOPS (p <= 0.03).

Droxidopa 126-130 coagulation factor II, thrombin Homo sapiens 43-51 18368304-11 2008 It also addresses the issue of whether addition of dopa decarboxylase inhibitors, when combined with l-dopa in the treatment of the motor deficit in Parkinson"s disease, impairs the pressor efficacy of Droxidopa. Droxidopa 202-211 dopa decarboxylase Homo sapiens 51-69 17603032-2 2007 The lipid dynamics near the gel-fluid transition, the chain length of saturated lipids and the presence of DOPE or DOPS in DOPC-vesicles modulate the aggregation kinetics of insulin in an indifferent, an aggregation-accelerating or an aggregation-inhibiting manner, subtly depending on the pH-value and the presence of salt. Droxidopa 115-119 insulin Homo sapiens 174-181 17603032-6 2007 Apart from weak dipole-dipole, dipole-monopole and hydrogen bonding interactions, the release of curvature elastic stress in mixed DOPC/DOPE-membranes and preferred interactions of insulin with carboxylic groups in DOPC/DOPS-membranes favour an increased surface accumulation. Droxidopa 220-224 insulin Homo sapiens 181-188 17603032-7 2007 At neutral pH, a partial insertion of insulin into the lipid bilayer is favoured, which accounts for the aggregation-inhibiting effect of all lipid bilayer systems studied except those containing DOPS. Droxidopa 196-200 insulin Homo sapiens 38-45 17603032-9 2007 The accelerating effect of DOPS on the aggregation of insulin under net electrostatic repulsion at pH 7.4 remains to be elucidated, yet, it might result from increased surface accumulation and/or faster/more extensive unfolding of the protein without a subsequent membrane insertion. Droxidopa 27-31 insulin Homo sapiens 54-61 17214596-9 2006 L-DOPS is very effective in treatment of deficiency of dopamine-beta-hydroxylase (DBH), the enzyme required for conversion of dopamine to NE in sympathetic nerves.

Droxidopa 0-4 dopamine beta-hydroxylase Homo sapiens 113-138 17017570-4 2006 DOPS pressor effect is due to its conversion to NE outside the central nervous system because concomitant administration of carbidopa, an inhibitor of AADC that does not cross the blood-brain barrier, blunted both the increase in plasma NE and the pressor response.

Droxidopa 24-57 nerve growth factor Mus musculus 93-112 8836986-5 1996 Only a minor part of L-threo-DOPS was metabolized into noradrenaline by aromatic L-amino acid decarboxylase, and it was metabolized mainly by two other enzymes, catechol-O-methyltransferase and DOPS-aldolase in the brain. Droxidopa 21-33 catechol-O-methyltransferase Homo sapiens 161-189 7834959-2 1994 Droxidopa is decarboxylated into NA by aromatic L-amino acid decarboxylase in the brain, but its effects on other monoamine neurotransmitters, such as dopamine (DA) and serotonin (5-HT) have not been systematically examined.

Droxidopa 0-9 dopa decarboxylase Homo sapiens 67-93 7834960-3 1994 Droxidopa, an artificial amino acid, is decarboxylated by aromatic L-amino acid decarboxylase (AADC) into NA. Droxidopa 0-9 dopa decarboxylase Homo sapiens 95-99 7834960-11 1994 In the intraventricular fluid, in addition to NA, a large amount of a metabolite of droxidopa by catechol-O-methyltransferase (COMT), 3-O-methoxy-droxidopa (3OMD), was detected, followed by the metabolites by DOPS-aldolase (DOPS-ALD), protocatechualdehyde and protocatechuic acid. Droxidopa 84-93 catechol-O-methyltransferase Homo sapiens 97-125 7834960-11 1994 In the intraventricular fluid, in addition to NA, a large amount of a metabolite of droxidopa by catechol-O-methyltransferase (COMT), 3-O-methoxy-droxidopa (3OMD), was detected, followed by the metabolites by DOPS-aldolase (DOPS-ALD), protocatechualdehyde and protocatechuic acid.

Droxidopa 53-62 catechol-O-methyltransferase Homo sapiens 82-86 8023359-1 1994 BACKGROUND AND PURPOSE: L-Threo-3,4-dihydroxyphenylserine (DOPS) is reported to increase the nerve growth factor (NGF) synthesis in cultured mouse L-M fibroblast and astroglial cells, and this effect is not blocked by treatment with decarboxylase inhibitor. Droxidopa 59-63 nerve growth factor Mus musculus 93-112 8023359-1 1994 BACKGROUND AND PURPOSE: L-Threo-3,4-dihydroxyphenylserine (DOPS) is reported to increase the nerve growth factor (NGF) synthesis in cultured mouse L-M fibroblast and astroglial cells, and this effect is not blocked by treatment with decarboxylase inhibitor. Droxidopa 59-63 nerve growth factor Mus musculus 114-117 8023359-3 1994 We evaluated the possible protective effect of DOPS against hippocampal CA1 cell death after transient forebrain ischemia in gerbils. Droxidopa 47-51 carbonic anhydrase 1 Mus musculus 72-75 8023359-8 1994 RESULTS: Preservation of the hippocampal CA1 cells was found in the brains treated with 300 mg/kg DOPS plus benserazide (neuronal density, 125 +/- 24 cells per millimeter) compared with the vehicle-treated ones (49 +/- 11 cells per millimeter) (P < .01). Droxidopa 98-102 carbonic anhydrase 1 Mus musculus 41-44 8023359-9 1994 The immunoreactive NGF was greatly reduced from 3 hours after recirculation in the vehicle group, but it was much less reduced in the 300-mg/kg-DOPS-plus-benserazide group as compared with the vehicle group. Droxidopa 144-148 nerve growth factor Mus musculus 19-22 8023359-10 1994 The immunoreactivity for NGF receptor was gradually induced from 1 hour after recirculation with the peak at 1 day in the vehicle group, but it was only slightly induced at 8 hours in the 300-mg/kg-DOPS-plus-benserazide group. Droxidopa 198-202 nerve growth factor receptor (TNFR superfamily, member 16) Mus musculus 25-37 8023359-12 1994 However, in the 300-mg/kg-DOPS-plus-benserazide group, the induction of HSP70 was found from 8 hours and was much less intensive. Droxidopa 26-30 heat shock protein 1B Mus musculus 72-77 8023359-13 1994 CONCLUSIONS: Treatment with DOPS is protective to the ischemic hippocampal CA1 cells, and the NGF-receptor system may play a role in this protective effect of DOPS. Droxidopa 28-32 carbonic anhydrase 1 Mus musculus 75-78 8023359-13 1994 CONCLUSIONS: Treatment with DOPS is protective to the ischemic hippocampal CA1 cells, and the NGF-receptor system may play a role in this protective effect of DOPS.

Droxidopa 159-163 carbonic anhydrase 1 Mus musculus 91-94 7936090-4 1994 In this study, we studied a possible protective effect of DOPS against the hippocampal CA1 cell death after transient forebrain ischaemia in gerbils in relation to the change of NGFR immunoreactivity. Droxidopa 58-62 carbonic anhydrase 1 Mus musculus 87-90 7936090-4 1994 In this study, we studied a possible protective effect of DOPS against the hippocampal CA1 cell death after transient forebrain ischaemia in gerbils in relation to the change of NGFR immunoreactivity. Droxidopa 58-62 nerve growth factor receptor (TNFR superfamily, member 16) Mus musculus 178-182 7936090-5 1994 We found that treatment with DOPS (300 mg kg-1) in combination with a decarboxylase inhibitor (benserazide, 10 mg kg-1) protected ischaemic hippocampal CA1 cell against delayed neuronal death (neuronal density = 125 +/- 24 mm-1) as compared to the treatment with vehicle (49 +/- 11 mm-1) (p < 0.01). Droxidopa 29-33 carbonic anhydrase 1 Mus musculus 152-155 7936090-8 1994 These data suggest that the protective role of DOPS on the ischaemic hippocampal CA1 cells may act through the NGF and its receptor system.

Droxidopa 31-35 dopa decarboxylase Homo sapiens 237-241 8414219-5 1993 The antioxidants, ascorbic acid and sodium pyrosulfite, completely prevented the stimulatory effect of L-DOPS, and radical scavengers (superoxide dismutase plus catalase) caused a significant partial inhibition of the response to L-DOPS. Droxidopa 103-109 catalase Homo sapiens 161-169 8414219-5 1993 The antioxidants, ascorbic acid and sodium pyrosulfite, completely prevented the stimulatory effect of L-DOPS, and radical scavengers (superoxide dismutase plus catalase) caused a significant partial inhibition of the response to L-DOPS. Droxidopa 230-236 catalase Homo sapiens 161-169 8486891-5 1993 Treatment with the synthetic amino acid, DL-threo-dihydroxyphenylserine, which is converted to noradrenaline by dopa-decarboxylase, resulted in a significant increase in blood pressure.
