In this study, tetrahydrocannabinols (THCs) were mainly oxidized at the 11-position and allylic sites at the 7alpha-position for Delta(8)-THC and the 8beta-position for Delta(9)-THC by human hepatic… Expand
Conversion of cannabidiol to Δ9-tetrahydrocannabinol and related cannabinoids in artificial gastric juice, and their pharmacological effects in mice
Cannabidiol (CBD), a nonpsychoactive cannabinoid, was found to be converted to 9α-hydroxyhexahydrocannabinol (9α-OH-HHC) and 8-hydroxy-iso-hexahydrocannabinol (8-OH-iso-HHC) together with… Expand
Involvement of human blood arylesterases and liver microsomal carboxylesterases in nafamostat hydrolysis.
- S. Yamaori, N. Fujiyama, +9 authors K. Watanabe
- Chemistry, Medicine
- Drug metabolism and pharmacokinetics
Metabolism of nafamostat, a clinically used serine protease inhibitor, was investigated with human blood and liver enzyme sources. All the enzyme sources examined (whole blood, erythrocytes, plasma… Expand
Marijuana extracts possess the effects like the endocrine disrupting chemicals.
The progesterone 17alpha-hydroxylase activity, which is one of the steroidogenic enzymes in rat testis microsomes, was significantly inhibited by crude marijuana extracts from… Expand

Damage to interstitial connective tissue is associated with the rapid accumulation of monocytes and neutrophils at the site of injury. To study the role of collagen fragments in neutrophil migration,… Expand
Delta(9)-Tetrahydrocannabinol enhances MCF-7 cell proliferation via cannabinoid receptor-independent signaling.
We recently reported that Delta(9)-tetrahydrocannabinol (Delta(9)-THC) has the ability to stimulate the proliferation of human breast carcinoma MCF-7 cells. However, the mechanism of action remains… Expand
Possible Existence of a Novel Receptor for Uridine Analogues in the Central Nervous System Using Two Isomers, N3-(S)-(+)- and N3-(R)-(−)-α-Hydroxy-β-phenethyluridines
Uridine analogue binding sites, the so-called uridine receptor, were observed in the experiments on specific [3H]N3-phenacyluridine binding to bovine synaptic membranes using two isomers, N3-(S)-(+)-… Expand
Effects of pentobarbital tolerance and dependence on convulsant and GABAA receptor antagonist binding.
Experiments were performed which examined the effects of pentobarbital tolerance and dependence on GABAA receptor antagonist binding. In rats implanted with pentobarbital pellets for 7 days, followed… Expand
Hepatic Metabolism of Methyl Anthranilate and Methyl N-Methylanthranilate as Food Flavoring Agents in Relation to Allergenicity in the Guinea Pig
To assess the safety of the food flavoring agents, methyl anthranilate (MA) and methyl N-methylanthranilate (MNMA), their relationships with metabolism and allergenicity were examined in guinea pigs.… Expand
Relative Estimation of the Radical Scavenging Activities of Agricultural Products.
To estimate the radical scavenging activity in various agricultural products, the rapid and reliable method is developed. There have been many methods to measure the radical scavenge activities so… Expand
