Studies on niacin biosynthesis from 3-hydroxyanthranilic acid in streptozotocin diabetic rats in vivo and in vitro.

چکیده
Biosynthesis of niacin from 3-hydroxyanthranilic acid (3-OHAA) in normal and streptozotocin diabetic rats was studied in vivo and in vitro. Streptozotocin (SZ) diabetic rats were found to excrete lesser quantities of 3-OHAA, quinolinic acid, niacin and N1-methylnicotinamide (nmn) in their urines following 3-OHAA administration than corresponding normal rats. In vitro studies indicated that SZ diabetic livers form less quinolinic acid from 3-OHAA than normal livers. It appears that this may be due to elevated picolinic carboxylase activity in the livers of SZ diabetic rats.

In 1945, Krehl et al. (1) observed that tryptophan and nicotinic acid were mutually interchangeable, within limits, in supporting the growth of rats. Since that time considerable evidence has accumulated which demonstrates the biosynthesis of niacin from tryptophan in the rat and other animals. Studies with Neurospora and mammals have demonstrated that the pathway from tryptophan goes through k...

متن کاملEffect of garlic (Allium sativum) extract on levels of urea and uric acid in normal and streptozotocin-diabetic rats
The effects of garlic bulbs alcoholic extract (Allium sativum) on the level of urea and uric acid were investigated in both normal and streptozotocin-induced diabetic rats. The normal and diabetic rats were administrated orally with the extract (100, 250, 500 mg/kg) or glibenclamide (600 mg/kg) for 14 days. Oral administration of the garlic extract (0.25 and 0.5 g/kg body wt.) for 14 days exhib...
متن کاملStudies on the Biological Activity of Nicotinylalanine, an Analogue of ICynurenine*
Considerable evidence has been obtained that 3-hydroxyanthranilic acid and quinolinic acid can be converted to niacin in the intact rat (2-9). The usually low yield of niacin from these compounds suggested that another pathway from tryptophan to niacin might exist. Thus, kynurenine or hydroxykynurenine might be converted to niacin through an intermediate such as y-(3-pyridyl)-y-oxo-ar-aminobuty...
