(2) The second 12 cases were given the same doses of DOB instead of DOA.
(3) The most behaviorally potent analogues examined, DOB, DOM, and 5-methoxy-N,N-dimethyltryptamine, were found to possess rather high affirmities (pA2 = 7.35, 7.12, and 7.08, respectively) for the 5-HT receptors of the model system.
(4) [82Br]-DOB has been suggested as a potential brain scanning agent for nuclear medicine; 3b would have the advantage over DOB of providing the superior gamma-ray imaging properties of 131I or 123I.

(7) The study was aimed at comparing the effects of dobutamine (dob) and dopamine (dop) on isotonic contraction and rhythmicity of isolated guinea-pig papillary muscles (in oxygenated Tyrode at 37 degrees C), by taking into account: 1) the rate of stimulation (50% above the diastolic threshold) at 5 fixed periods: (RR: 1600, 1200, 1000, 800 and 400 ms); 2) 7 log concentrations (logC) of the index amine (from 10(-9) to 10(-3) M).
(8) Our results suggest that even in case of hypothermia, DOB retains a selective inotropic effect with no threat of arrhythmogenicity, and produces stable hemodynamics.

(12) In both systems, expression of this single serotonin receptor cDNA led to the appearance of both [3H]DOB and [3H]ketanserin binding sites with properties that matched their binding characteristics in mammalian brain homogenates.
(13) In competition experiments 8-OH-DPAT, TFMPP, mesulergine, DOB, and ICS 205-930 had low affinity for 3H-5HT-labeled 5HT1D sites, indicating that the pharmacology of the 5HT1D site is distinct from previously identified 5HT1A, 5HT1B, 5HT1C, 5HT2, and 5HT3 sites.
(14) Chronic DOB infusion was without effect on CRF concentrations in all hypothalamic and extrahypothalamic brain regions studied.
(15) This effect was apparently associated with down-regulation of the 5-HT2 receptor because high-affinity cortical [3H]DOB and hypothalamic (+-)-[125I]-1-(2,5-dimethoxy-4-iodophenyl)-2-amino-propane binding were decreased at this time as well.
(16) The effects of the 5-HT2-selective agonists 1-(4-bromo-2,5-dimethoxyphenyl)-2-aminopropane (DOB) and 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) on cat platelet aggregation were investigated and compared with those produced by serotonin (5-HT) and a positional isomer of DOB (i.e., isoDOB).
(17) (4) The Dob IgG is relatively resistant to digestion with papain and trypsin; however, it is readily digested with pepsin, although at an unusual site.
(18) In contrast, specific [3H]DOB binding cannot be detected in bovine cortical membranes.
(19) Classical serotonin antagonists, most of which are rather selective for 5-HT2 sites, and 5-HT2-selective antagonists are able to block the stimulus effects of DOM, DOB, and DOI, but not those of 8-OH DPAT or TFMPP.
(20) (3) The Dob heavy chain has three fewer residues of half-cystine than expected in gamma1 chains.
Dop

(2) This study evaluated the in vitro renin release, tissue cyclic AMP content (TcAMPc), and tissue renin content (TRC) changes with time, in response to administration of dopamine (DOP) and of the dopamine-receptor blocking agent pimozide (PIM) to renal cortical slices from sodium deficient (SD) rats.
(3) We suggest that the OH improved mainly because of the increase in MSA due to L-threo-DOPS, and that the drug may activate sympathetic outflow at a site proximal to the sympathetic ganglion.

(6) Intracellular PLP levels were higher in the 11 mM Glc group than in the other groups with and without DOP, and DOP with 11 mM Glc increased PLP levels (DOP N2 vs. DOP O2).
(7) L-DOPS alone was administered in 4 patients, and combined with L-DOPA or bromocriptine in 6 patients.
(8) The slight diminution of this increase when (+)-erythro-DOPS was administered after inhibition of peripheral decarboxylase, might result from the algebraic sum of two inversely acting processes: suppression of NE synthesis in the capillary walls and enhancement of parenchymatous NE in some brain areas.
(9) In comparative studies the extracerebral decarboxylase was inhibited with serinetrihydroxybenzylhydrazide (RO 4-4602) before injection of DOPA or DOPS.
