Streptozotocin

Biological Activity

Streptozotocou (STZ) is a kind of glucosamine - nitrosourea derivative.

Solution is extremely unstable at room temperature, and can be decomposed into gas and volatilized after half an hour, freshly prepared is recommended.

	Method	creating diabetic mice models
	Cell Lines	diabetic mice
	Concentrations	-
	Incubation Time	24 h
	Results	Remarkably, the fluorescence intensity of skin treated by non-crosslinked gelatin MNs decreased more sharply compared with crosslinked RS-PGC-MNs.

	Method	intraperitoneal injection
	Cell Lines	Balb/c mice
	Concentrations	100 mg/kg
	Incubation Time	48h
	Results	Figure 6(a-b) shows the in-vivo fluorescence images of Balb/c mice after treatment of different molecular weight of PVA, gelatin, chitosan and HA based MNs array at different time (0, 1, 2, 3, 4, 5, and 8 h) intervals of drug release.

	Method	inject to mice
	Cell Lines	Female Balb/c mice
	Concentrations	10 mg/ml
	Incubation Time	48 h
	Results	The amount of drugs loaded in RSMNs with various length of PLA 182 MNs was approximately 280 ng/patch.

	Method	Prior to the experiment, the diabetic model was induced in BALB/c female mice (6–8 weeks old, 16  0.7 g) with streptozotocin (200 mg/kg in sodium citrate buffer, PH 4.5) administrated by intraperitoneal injection aer they were fasted for 6 h only in case of water.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Species	Mouse	Rat	Rabbit	Guinea pig	Hamster	Dog
Weight (kg)	0.02	0.15	1.8	0.4	0.08	10
Body Surface Area (m2)	0.007	0.025	0.15	0.05	0.02	0.5
Km factor	3	6	12	8	5	20

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km
	Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the K_m factor for a mouse and then divide by the K_m factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
