1000700-26-4 Usage
Uses
ATB-343 is a hybrid molecule of the NSAID indomethacinan and an H2S donor.
Biological Activity
atb-343, also named as indomethacin, is an h2s-releasing derivative of indomethacin [1].hydrogen sulfide (h2s) is a newly recognized signaling molecule with potent cytoprotective actions. hydrogen sulfide has been involved in mediating many physiological processes, such as the maintenance of gastrointestinal mucosal defense and repair. hydrogen sulfide also exerts many anti-inflammatory effects, including inhibition of leukocyte adherence to the vascular endothelium and leukocyte migration to sites of inflammation [2].
in vitro
indomethacin enhanced the nk cell activity in vitro by blocking the prostaglandin production of monocytes [3].
in vivo
in rats, oral administration of atb-343 significantly inhibited gastric prostaglandin synthesis and systemic cox-1 activity [1]. indomethacin was a potent inhibitor of prostaglandin synthesis. indomethacin suppressed in vivo thyroid hormone secretion and cholera toxin-induced intestinal fluid accumulation. indomethacin in submicromolar concentrations inhibited cyclic amp-dependent protein kinase and endogenous protein phosphorylation [4].

Check Digit Verification of cas no
The CAS Registry Mumber 1000700-26-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,7,0 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1000700-26:
(9*1)+(8*0)+(7*0)+(6*0)+(5*7)+(4*0)+(3*0)+(2*2)+(1*6)=54
54 % 10 = 4
So 1000700-26-4 is a valid CAS Registry Number.
