Cochlearine
Cochlearines A can significantly inhibit Cav3.1 T-type calcium channel (TTCC) and show noticeable selectivity against Cav1.2, Cav2.1, Cav2.2, and Kv11.1 (hERG) channels; and TTCC inhibitors hold great potential for the treatment of a variety of neurological disorders.

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.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Two New Classes of T-Type Calcium Channel Inhibitors with New Chemical Scaffolds from Ganoderma cochlear[Pubmed:
26024438]
T-type calcium channel (TTCC) inhibitors hold great potential for the treatment of a variety of neurological disorders.
METHODS AND RESULTS:
Cochlearoids A-E (1-5), five pairs of dimeric meroterpenoid enantiomers, and Cochlearines A (6) and B (7), two pairs of enantiomeric hybrid metabolites, were isolated and characterized from Ganoderma cochlear.
CONCLUSIONS:
Biological evaluation found that compounds (+)-1, (-)-3, and (±)-6 significantly inhibited Cav3.1 TTCC and showed noticeable selectivity against Cav1.2, Cav2.1, Cav2.2, and Kv11.1 (hERG) channels.

Brassicaceae contain nortropane alkaloids.[Pubmed:
16884746]
The report of Cochlearine, the 3-hydroxybenzoate ester of tropine found in Cochlearia officinalis, Brassicaceae, initiated a screening for tropane alkaloids in Cochlearia species and for calystegines in further Brassicaceae.
METHODS AND RESULTS:
All ten Cochlearia species investigated contained Cochlearine, tropine, and pseudotropine. Calystegines, nortropane alkaloids deriving from pseudotropine, were also identified in all Cochlearia species and accumulated up to 0.5% dry mass in leaves. Brassicaceae species of all major lineages of the family were analysed for calystegines. Of the 43 species included in the study, 18 accumulated calystegines of various structures. This is the first screening of Brassicaceae for products of the tropane alkaloid pathway, which is known as characteristic for plants of Solanaceae family.
CONCLUSIONS:
The identification of calystegines in all branches of the Brassicaceae family including Aethionema, a species at the basis of the family, suggests tropane alkaloids as secondary compound typical for Brassicaceae.
