Davalintide
Based on 1 Customer Validation
Davalintide is an Amylin (HY-P1464)-mimetic peptide with greater potency and longer-lasting effects. Davalintide is a potent agonist of amylin receptor (IC50 = 0.04 nM), calcitonin receptor (IC50 = 0.06 nM) and calcitonin related peptide receptor (CGRP receptor) (IC50 = 3.1 nM). Davalintide shows stronger potency to Amylin to activate cyclic AMP production through the calcitonin receptor (EC50 = 1.4 nM). Davalintide regulates blood sugar and weight through various mechanisms such as delaying gastric emptying, inhibiting glucagon secretion, and reducing food intake. Davalintide can be used for the studies of anti-obesity and anti-diabetes.

Davalintide (1-100 μg/kg, i.p., single dose) does not affect the autonomous activities when food intake is reduced in rats, and its inhibitory effect on appetite is not mediated by adverse reactions such as nausea or aversion[1].
Davalintide (1-100 μg/kg, s.c., once daily, continuous infusion for 8 weeks) effectively reduces rats food intake and body weight with the weight loss mainly specific to fat reduction, while lean body mass preserved, and it has metabolic benefits that go beyond simply restricting food intake[1].
Davalintide (10 μg/kg, s.c., once daily, continuous infusion for 4 weeks) significantly reduces total calorie intake, decreases the preference for high-fat and tasty foods, and prompts rats to choose the standard feed[1].
Davalintide (10 μg/kg, i.p., single dose) relies on the Area Postrema and achieves the effect of suppressing obesity by more persistently activating the downstream neural pathways in rats[1].
Davalintide (10 μg/kg, s.c., single dose) significantly inhibits the increase in glucagon caused by arginine stimulation in anesthetized rats, and the inhibitory effect on glucagon is specific[2].

-
Animal Model:Acute food intake inhibition experiment established in fasted overnight NIH Swiss mice (24-30 g) and overfed Sprague-Dawley (SD) rats (weighing 394-461 g)[1]
-
Dosage:1.09-1087 μg/kg (mice); 5 μg/kg (rats)
-
Administration:Intraperitoneal injection (i.p.), single dose
-
Result:And Amylin both significantly and dose-dependently inhibited acute food intake (mice ED50: 87 μg/kg vs. Amylin 110 μg/kg) Exhibited the duration of action significantly longer than that of Amylin (23 hours vs. 6 hours) in the experiment where obese rats were subjected to the dark cycle (the main feeding period).
-

-
Dosage:1, 10, 100 μg/kg
-
Administration:Intraperitoneal injection (i.p.), single dose
-
Result:Dose-dependently and persistently reduced food intake and body weight (8-week ED50 = 1.2 μg/kg/day).
Significantly reduced the level of plasma triglycerides.
-
Animal Model:Continuous infusion experiment (metabolic effect) established in obese rats induced by diet (Levin or SD rats, ~464 g), maintained on a 32% high-fat diet[1]
-
Dosage:1, 3, 10, 100 μg/kg
-
Administration:Subcutaneous injection (s.c.), once daily for 8 weeks
-
Result:Dose-dependently and persistently reduced food intake and body weight (8-week ED50 = 1.2 μg/kg/day).
Significantly reduced the level of plasma triglycerides.
-
Animal Model:Food preference experiment established in DIO rats (~ 515 g) provided with both standard feed and 32% high-fat feed for them to choose freely[1]
-
Dosage:10 μg/kg
-
Administration:Subcutaneous injection (s.c.), once daily for 4 weeks
-
Result:Significantly reduced total calorie intake.
Significantly reduced the preference for high-fat and delicious foods, and prompted the animals to choose standard feed.
-
Animal Model:Energy metabolism experiment established in SD rats (~ 421 g), maintained on a 32% high-fat diet for 5 weeks[1]
-
Dosage:30 μg/kg
-
Administration:Subcutaneous injection (s.c.), once daily for 4 weeks
-
Result:Exhibited the energy consumption (VO₂) of not different from that in the Vehicle group.
Slight but significant increased RQ values at the end of the second week.
-
Animal Model:Area postrema (AP) damage experiment established in SD rats (weighing 175-200 g) underwent AP lesion surgery or sham surgery, and the experiments were conducted several months after recovery[1]
-
Dosage:10 μg/kg

Administration:Intraperitoneal injection (i.p.), single dose
-
Result:Significantly reduced food intake in the sham operation group.
Completely eliminated the effect of suppressing appetite in the AP lesion group.
