Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Anticancer Candidates Derived from Natural Cinnamic Acids.[Pubmed:
25634446]
Cancer is the most dangerous disease that causes deaths all over the world. Natural products have afforded a rich source of drugs in a number of therapeutic fields including anticancer agents. Many significant drugs have been derived from natural sources by structural optimization of natural products. Cinnamic acid has gained great interest due to its antiproliferative, antioxidant, antiangiogenic and antitumorigenic potency.
METHODS AND RESULTS:
Currently, cinnamic acid and its analogs such as caffeic acid, sinapic acid, ferulic acid, and isoferulic acid(3-Hydroxy-4-methoxycinnamic acid) display various pharmacological activities, such as immunomodulation, anti-inflammation, anticancer and antioxidant. They have served as a major source of potential anticancer lead compounds.
CONCLUSIONS:
In this review, we focus on the anticancer potency of cinnamic acid derivatives and novel strategies for the design of these derivatives. We hope this review will be useful for researchers who are interested in developing anticancer agents.

Evaluation of antioxidant activity of isoferulic acid in vitro.[Pubmed:
21941899]
Isoferulic acid (3-Hydroxy-4-methoxycinnamic acid, IFA), the isomer of ferulic acid (4-hydroxy-3-methoxycinnamic acid), is a rare phenolic acid occurring in Rhizoma Cimicifugae. Unlike ferulic acid, which has been well investigated, the antioxidant activity of 3-Hydroxy-4-methoxycinnamic acid has not been measured.
METHODS AND RESULTS:
In this study, 3-Hydroxy-4-methoxycinnamic acid was systematically evaluated for its in vitro antioxidant activity for the first time. IC50 values were calculated of 7.30 +/- 0.57, 4.58 +/- 0.17, 1.08 +/- 0.01, 8.84 +/- 0.43, 7.69 +/- 0.39, 1.57 +/- 0.2, 13.33 +/- 0.49 microg/mL, respectively, for lipid peroxidation, DPPH (1,1-diphenyl-2-picrylhydrazyl radical) and ABTS (3-ethylbenzthiazoline-6-sulfonic acid diammonium salt) radical scavenging, reducing power on Fe3+ and CU2+ ions, and hydroxyl and superoxide anion radical scavenging.
CONCLUSIONS:
Comparison with the IC50 values with those of the positive controls, Trolox and butylated hydroxyanisole (BHA), it can be concluded that 3-Hydroxy-4-methoxycinnamic acid is an effective natural antioxidant in both lipid and aqueous media.

Kinetics governing the inhibitory effect of 3-hydroxy-4-methoxycinnamic acid on tyrosinase-catalyzed reactions[Reference:
WebLink]
METHODS AND RESULTS:
The kinetics governing the inhibitory effect of 3-Hydroxy-4-methoxycinnamic acid on the activities of monophenolase and diphenolase in tyrosinase were studied using an enzymological kinetic analysis method, in a Na2HPO4-NaH2PO4 buffer system (pH=6.8) at 30℃. The 3-Hydroxy-4-methoxycinnamic acid was observed to efficiently inhibit tyrosinase monophenolase and diphenolase activities. Approximately 0.13 mmol/L and 0.39 mmol/L 3-Hydroxy-4-methoxycinnamic acid caused a 50% rate inhibition (IC50) in monophenolase and diphenolase activities, respectively; these values were much lower than that of arbutin (IC50=5.3 mmol/L for diphenolase activity). The presence of 3-Hydroxy-4-methoxycinnamic acid also prolonged the lag period of monophenolase; the presence of 0.20 mmol/L 3-Hydroxy-4-methoxycinnamic acid resulted in a lag period of 4.3 min, compared to the 1.1 min lag period of monophenolase in the absence of 3-Hydroxy-4-methoxycinnamic acid. The inhibition of diphenolase by 3-Hydroxy-4-methoxycinnamic acid appeared to be reversible.
CONCLUSIONS:
This indicated that the inhibitor suppresses the enzyme activity, resulting in a reduction in catalysis efficiency, as opposed to removing the effective enzyme, which leads to a reduction in enzyme activity. The Lineweaver-Burk plot demonstrated the competitive inhibition of tyrosinase by 3-Hydroxy-4-methoxycinnamic acid, with a maximum reaction rate (vm) and inhibition constant (KI) of 64.5 μmol/min and 0.11 mmol/L, respectively.
