General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

The synthesis, distribution, and anti-hepatic cancer activity of YSL.[Pubmed:15336278]

Bioorg Med Chem. 2004 Sep 15;12(18):4989-94.

YSL was prepared stepwise from C terminal to N terminal with the side chain un-protective amino acids, Boc-Leu-OMe, Boc-Ser-OH, and Boc-Tyr-OH, as the starting materials in 39.5% total yield (31.2g/per batch). With the side chain un-protective Boc-(3,5-dibromo)-Tyr-OH and HCl.Ser-Leu-OMe as the starting materials (3,5-(3)H-Tyr)-Ser-Leu-OH was obtained in 29% yield. The determination of radioactive quantity in the urine and feces indicated that even after the administration for 130 h only 8.4% (5.35% in urine and 3.05% in feces) of total radioactive quantity from the metabolite of [3,5-(3)H-Tyr]-Ser-Leu-OH were monitored. The distribution study revealed the relative accumulation level of the individual tissue was arranged in the sequence of spleen>liver>kidney>lung>heart>muscle>brain. Selecting hepatic cancer as the target YSL significantly increased the survival time of H22 tumor cells implanted mice.

Amino acids and peptides. LII. Design and synthesis of opioid mimetics containing a pyrazinone ring and examination of their opioid receptor binding activity.[Pubmed:9775433]

Chem Pharm Bull (Tokyo). 1998 Sep;46(9):1374-82.

An amino group was introduced to the 3 or 6 position of a pyrazinone ring by cyclization of dipeptidyl chloromethyl ketones. Boc-Tyr-OH was coupled with the amino function, followed by removal of the Boc group to give pyrazinone ring-containing tyrosine derivatives. Of the various tyrosine derivatives prepared, 5-methyl-6-beta-phenethyl-3-tyrosylaminobutyl-2(1H)-pyrazinone exhibited strong binding to the mu-opioid receptor with a Ki value of 55.8 nM and to the delta-opioid receptor with a Ki value of 2165 nM and with a Ki mu/Ki delta value of 0.026.

An efficient synthesis of N-tert-butoxycarbonyl-O-cyclohexyl-L-tyrosine.[Pubmed:11217115]

Chem Pharm Bull (Tokyo). 2001 Feb;49(2):233-5.

A facile and efficient synthesis of N-tert-butoxycarbonyl-O-cyclohexyl-L-tyrosine [Boc-Tyr(Chx)-OH] is described. Boc-Tyr-OH was treated with NaH in dimethylformamide and then with 3-bromocyclohexene to give N-Boc-O-(cyclohex-2-enyl)-L-tyrosine [Boc-Tyr(Che)-OH] in 70% yield. Hydrogenation of Boc-Tyr(Che)-OH over PtO2 afforded Boc-Tyr(Chx)-OH in almost quantitative yield. The highest yield was achieved when a side product in the synthesis of Boc-Tyr-OH, Boc-Tyr(Boc)-OH, was not removed, because it was also converted to Boc-Tyr(Che)-OH without any additional manipulations. The new synthetic method described here is convenient for practical use, and would facilitate the widespread use of the Chx group for the hydroxy-protection of Tyr.
