HU-345
HU-345 (cannabinol quinone) is a drug that is able to angiogenesis inhibitor, inhibit aortic ring angiogenesis more potently than its parent compound cannabinol (CBN). It exhibits no psychoactive effects on the body. HU-345 can be derived through the oxidative degradation of CBN. See also *HU-331 HU-331 is a quinone anticarcinogenic drug synthesized from cannabidiol, a cannabinoid in the ''Cannabis sativa'' plant. It showed a great efficacy against oncogenic human cells.

Cannabinol
Cannabinol (CBN) is a mildly psychoactive phytocannabinoid that acts as a low affinity partial agonist at both CB1 and CB2 receptors. This activity at CB1 and CB2 receptors constitutes interaction of CBN with the endocannabinoid system (ECS). Although CBN shares the same mechanism of action as other phytocannabinoids (e.g., Delta-9-tetrahydrocannabinol, Δ9-THC), it has a lower affinity for CB1 receptors, meaning that much higher doses of CBN are required in order to experience effects, such as mild sedation. It was the first cannabinoid to be isolated from cannabis and was discovered in 1896. Pharmacology Pharmacodynamics Both THC and CBN activate the CB1 (Ki = 211.2 nM) and CB2 (Ki = 126.4 nM) receptors. Each compound acts as a low affinity partial agonist at CB1 receptors with THC demonstrating 5x–10× greater affinity to the CB1 receptor. Like THC, CBN has a higher selectivity for CB2 receptors which are located throughout the central and peripheral nerv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HU-331
HU-331 is a quinone anticarcinogenic drug synthesized from cannabidiol, a cannabinoid in the ''Cannabis sativa'' plant. It showed a great efficacy against oncogenic human cells. HU-331 does not cause arrest in cell cycle, cell apoptosis or caspase activation. HU-331 inhibits DNA topoisomerase II even at nanomolar concentrations, but has shown a negligible effect on the action of DNA topoisomerase I. The cannabinoid quinone HU-331 is a very specific inhibitor of topoisomerase II, compared with most known anticancer quinones. One of the main objectives of these studies is the development of a new quinone derived compound that produces anti- neoplasm, neoplastic activity while maintaining low toxicity at therapeutic doses. Mechanism of action Inhibitors of topoisomerases can act at two different levels. First inhibiting topoisomerase, which stabilize the topoisomerase-DNA complex and thus introduce DNA breaks in the wires that lead to apoptosis, then inhibiting the catalytic act ...

HU-336
HU-336 is a strongly antiangiogenic compound, significantly inhibiting angiogenesis at concentrations as low as 300 nM. It inhibits angiogenesis by directly inducing apoptosis of vascular endothelial cells without changing the expression of pro- and antiangiogenic cytokine Cytokines () are a broad and loose category of small proteins (~5–25 kDa) important in cell signaling. Cytokines are produced by a broad range of cells, including immune cells like macrophages, B cell, B lymphocytes, T cell, T lymphocytes ...s and their receptors. HU-336 is highly effective against tumor xenografts in nude mice. Although it is technically the oxidized quinone of delta-8 THC, it is entirely non psychoactive.

HU Cannabinoids
A research group led by Raphael Mechoulam at Hebrew University has synthesized many cannabinoids. Some of those are: * HU-210 — a high affinity CB1 agonist (''K''i = 0.23 nM) * HU-211 — the (+)-enantiomer of HU-210 with dramatically reduced CB1 affinity * HU-239 — also known as ajulemic acid * HU-243 * HU-308 * HU-320 * HU-331 * HU-336 * HU-345 See also * List of AM cannabinoids * List of CP cannabinoids * List of JWH cannabinoids The John W. Huffman research group at Clemson University synthesized over 450 cannabinoids. Some of those are: [Baidu] |
Quinone
The quinones are a class of organic compounds that are formally "derived from aromatic compounds benzene.html" ;"title="uch as benzene">uch as benzene or naphthalene] by conversion of an even number of –CH= groups into –C(=O)– groups with any necessary rearrangement of double bonds", resulting in "a fully Conjugated system, conjugated cyclic diketone, dione structure". The archetypical member of the class is 1,4-benzoquinone or cyclohexadienedione, often called simply "quinone" (thus the name of the class). Other important examples are 1,2-benzoquinone (''ortho''-quinone), 1,4-naphthoquinone and 9,10-anthraquinone. The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. Quinic acid, like quinine is obtained from cinchona bark, called quinaquina in the indigenous languages of Peruvian tribes. Properties Quinones are oxidized derivatives of aromatic compounds an ...

Angiogenesis Inhibitor
An angiogenesis inhibitor is a substance that inhibits the growth of new blood vessels (angiogenesis). Some angiogenesis inhibitors are endogenous and a normal part of the body's control and others are obtained exogenously through pharmaceutical drugs or diet. While angiogenesis is a critical part of wound healing and other favorable processes, certain types of angiogenesis are associated with the growth of malignant tumors. Thus angiogenesis inhibitors have been closely studied for possible cancer treatment. Angiogenesis inhibitors were once thought to have potential as a "silver bullet" treatment applicable to many types of cancer, but the limitations of anti-angiogenic therapy have been shown in practice. Currently, angiogenesis inhibitors are recognized for their improvement of cancer immunotherapy by overcoming endothelial cell anergy. Angiogenesis inhibitors are also used to effectively treat macular degeneration in the eye, and other diseases that involve a proliferatio ...

Aortic Ring
A vascular ring is a congenital defect in which there is an abnormal formation of the aorta and/or its surrounding blood vessels. The trachea and esophagus are completely encircled and sometimes compressed by a "ring" formed by these vessels, which can lead to breathing and digestive difficulties. Most often this is because of persistence of the double aortic arch after the second month of fetal life. Presentation The two arches surround the esophagus and trachea which, if sufficiently constrictive, may cause breathing or swallowing difficulties despite medical therapies. A less common ring is present with a right aortic arch instead of the usual left-sided aortic arch. This compresses the esophagus and trachea because of the persistence of a ductal ligament (from fetal circulation) that may connect between the aorta on the front and the left subclavian artery posteriorly going to the left arm. Symptoms Diagnosis Infants with vascular rings typically present before 12 months wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiogenesis
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature mainly by processes of sprouting and splitting, but processes such as coalescent angiogenesis, vessel elongation and vessel cooption also play a role. Vasculogenesis is the embryonic formation of endothelial cells from mesoderm cell precursors, and from neovascularization, although discussions are not always precise (especially in older texts). The first vessels in the developing embryo form through vasculogenesis, after which angiogenesis is responsible for most, if not all, blood vessel growth during development and in disease. Angiogenesis is a normal and vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. However, it is also a fundamental step in the transition of tumors from a benign state to a malign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
