PGB1

(13345-51-2)
This eicosanoid (FWB1 (free-acid) = 336.47 g/mol; CAS 13345-51-2, for PGB1, and 39306-29-1, for Bx) is a metabolite of prostaglandin E1: prostaglandin Bx is an oligomer of prostaglandin B1. The X-ray crystal structure of prostaglandin B1 suggests this prostaglandin has an unusual L-shaped configuration, with the a and w side chains roughly perpendicular to one another. The 15-hydroxyl group, which is normally directed away from the centroid of the prostaglandin in the standard hairpin mod

Citreoviridin

(25425-12-1)
Citreoviridin is a mycotoxin isolated from several Penicillium species that has been shown to inhibit the mitochondrial ATP synthetase system. It inhibits soluble ATPase (KD = 4.1 μM), ADP-stimulated respiration in isolated rat liver mitochondria (KD = 0.15 μM), and ATP-driven reduction of NAD+ by succinate (KD = 2 μM). Citreoviridin has been used to target ectopic ATPase activity in cancer cells in order to modulate the metabolic activity associated with tumorigenesis.[Cayman Chemical]

In the analysis work, it is often necessary to use a compound of good quality and accurate content, which is used as a comparison for detection control, or used to calibrate the instrument. This compound is called a standard. Or standard. The standard product refers to the standard substance used to determine the potency of biological products. The production department must provide the standard product expressed in units (μ) of its potency when it is approved as a quality standard for biological products. According to the application, the standard products for inspection can be divided into biological standard products for biological verification of biological products, endocrine drugs, antibiotics and so on.
