N-(5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)acetamide (Tamibarotene), also known as Am80, is a synthetic retinoid derivative and a member of the retinoid family of drugs. It is characterized by its unique chemical structure and high affinity for selective retinoic acid receptors (RARs), particularly RARα and RARβ. Tamibarotene is known for its role in regulating gene expression and promoting the differentiation of promyelocytic leukemic cells into mature granulocytes, effectively inhibiting the growth of cancer cells. Its lower toxicity compared to other retinoids makes it a promising candidate for various therapeutic applications.

139162-43-9 Usage

Uses

Used in Oncology:
Tamibarotene is used as a therapeutic agent for the treatment of acute promyelocytic leukemia (APL). It functions as a selective retinoic acid receptor (RAR) agonist, modulating gene expression and promoting the differentiation of promyelocytic leukemic cells into mature granulocytes, thereby inhibiting the growth of cancer cells. Its higher affinity for RARα and RARβ, along with its lower toxicity, makes it an effective treatment option for APL patients.
Used in Drug Development for Other Cancers:
Research has suggested that Tamibarotene may have potential therapeutic applications for other types of cancer. Its ability to regulate gene expression and promote cell differentiation could make it a valuable candidate for the development of targeted therapies against various malignancies.
Used in Dermatology:
Tamibarotene has also shown potential for use in the treatment of various dermatological conditions. Its effects on cell differentiation and gene regulation could be beneficial in managing skin disorders and improving skin health.
Used in Pharmaceutical Research:
As a synthetic retinoid derivative with unique properties, Tamibarotene serves as an important subject of pharmaceutical research. Its high affinity for RARs and lower toxicity compared to other retinoids make it a promising candidate for the development of new drugs and therapies for a range of medical conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 139162-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139162-43:
(8*1)+(7*3)+(6*9)+(5*1)+(4*6)+(3*2)+(2*4)+(1*3)=129
129 % 10 = 9
So 139162-43-9 is a valid CAS Registry Number.

The cubane paradigm in bioactive molecule discovery: Further scope, limitations and the cyclooctatetraene complement

Houston, Sevan D.,Fahrenhorst-Jones, Tyler,Xing, Hui,Chalmers, Benjamin A.,Sykes, Melissa L.,Stok, Jeanette E.,Farfan Soto, Clementina,Burns, Jed M.,Bernhardt, Paul V.,De Voss, James J.,Boyle, Glen M.,Smith, Maree T.,Tsanaktsidis, John,Savage, G. Paul,Avery, Vicky M.,Williams, Craig M.

The cubane phenyl ring bioisostere paradigm was further explored in an extensive study covering a wide range of pharmaceutical and agrochemical templates, which included antibiotics (cefaclor, penicillin G) and antihistamine (diphenhydramine), a smooth muscle relaxant (alverine), an anaesthetic (ketamine), an agrochemical instecticide (triflumuron), an antiparasitic (benznidazole) and an anticancer agent (tamibarotene). This investigation highlights the scope and limitations of incorporating cubane into bioactive molecule discovery, both in terms of synthetic compatibility and physical property matching. Cubane maintained bioisosterism in the case of the Chagas disease antiparasitic benznidazole, although it was less active in the case of the anticancer agent (tamibarotenne). Application of the cyclooctatetraene (COT) (bio)motif complement was found to optimize benznidazole relative to the benzene parent, and augmented anticancer activity relative to the cubane analogue in the case of tamibarotene. Like all bioisosteres, scaffolds and biomotifs, however, there are limitations (e.g. synthetic implementation), and these have been specifically highlighted herein using failed examples. A summary of all templates prepared to date by our group that were biologically evaluated strongly supports the concept that cubane is a valuable tool in bioactive molecule discovery and COT is a viable complement.

Method for preparing benzoic acid derivatives

-

, (2008/06/13)

This invention relates to a synthesis method favorable for the industrial production of a benzoic acid derivative having a retinoid activity of the general formula: STR1 wherein the derivative can be obtained by a simple procedure in safety with high yield.Specifically, this invention relates to a synthesis method characterized in that only one vessel is needed for several reactions in the different steps of subjecting acetanilide as a starting material, which is readily available and safe to handle, to Friedel-Crafts reaction with 2,5-dimethyl-2,5-dichlorohexane; subjecting the thus obtained compound to acyl exchange reaction with monomethyl ester terephthalic chloride, followed by hydrolysis; and recrystallizing from a mixture of methanol and water.Moreover, the crystals in novel form obtained by the synthesis method of this invention are suitable for formulation, because the amount of solvents remaining therein after recrystallization is small and the grain size thereof is uniform.
