60-70-8 Usage
Description
This alkaloid occurs naturally in Veratrum grandi/lorum and V. viride and is
also formed during the hydrolysis of Veratrosine (q.v.). It forms colourless
crystals of the monohydrate from aqueous EtOH and has [α]19D - 70° (MeOH).
The hydrochloride forms colourless plates from EtOH, m.p. 20l-2°C and the
picrate, yellow plates, m.p. 217.5 - 218°C. Two non-phenolic hydroxyl groups
and an imino group are present and the triacetyl derivative, m.p. 205.5-206°C;
[α]14.5D + 37.8° (MeOH), on controlled hydrolysis furnishes the N-acetyl com_x0002_pound, m.p. 176-8°C. The O-acetate has also been prepared as colourless prisms
from aqueous EtOH, m.p. 20l-2°C but it is still uncertain which of the hydroxyl
groups is acetylated in this derivative. Treatment with methyl iodide in MeOH in
the presence of sodium carbonate gives N-methylveratraminc methiodide, m.p.
268°C (dec.) from which the methochloride, m.p. 277°C can be obtained. On
catalytic hydrogenation, the base furnishes the dihydro derivative, m.p. 198-
200°C; [α]27D + 27.4°, which forms the N-acetyl compound, m.p. 220-3°C;
[α]28D + 81° and the triacetyl derivative, m.p. l89.5-190.5°C; [α]24D + 84°.

Uses
Different sources of media describe the Uses of 60-70-8 differently. You can refer to the following data:
1. It is useful as signal transduction inhibitor for treating tumors
2. The hedgehog (Hh) signaling pathway, which is blocked by cyclopamine , plays a key role in morphogenesis and has potential applications in the treatment of cancer. Veratramine, a teratogenic steroidal alkaloid isolated from the corn lily (Veratrum sp.), is an analog of cyclopamine that can inhibit the Hh signaling-dependent proliferation of NIH/3T3 cells at 8 μM. Additionally, veratramine has anti-thrombotic activity as it dose dependently inhibits platelet aggregation in rabbits ex vivo. While it may be most useful as a signal transduction inhibitor for treating tumors, veratramine also induces serotonin release and inhibits its re-uptake in the CNS.

Check Digit Verification of cas no
The CAS Registry Mumber 60-70-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 60-70:
(4*6)+(3*0)+(2*7)+(1*0)=38
38 % 10 = 8
So 60-70-8 is a valid CAS Registry Number.
