Check Digit Verification of cas no

The CAS Registry Mumber 18355-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,5 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18355-96:
(7*1)+(6*8)+(5*3)+(4*5)+(3*5)+(2*9)+(1*6)=129
129 % 10 = 9
So 18355-96-9 is a valid CAS Registry Number.

Process improvement in the production of a pharmaceutical intermediate using a reaction calorimeter for studies on the reaction kinetics of amination of a bromopropyl compound

Sano, Takahiro,Sugaya, Toru,Kasai, Masaji

, p. 169 - 174 (1998)

A synthetic process to produce a pharmaceutical intermediate, [3-(dimethylamino)propyl]triphenylphosphonium bromide (1), was established in the laboratory. Process safety evaluations did not show any severe problems. In order to scale up to plant scale, w

Chlorpheniramine Analogues Reverse Chloroquine Resistance in Plasmodium falciparum by Inhibiting PfCRT

Deane, Karen J.,Summers, Robert L.,Lehane, Adele M.,Martin, Rowena E.,Barrow, Russell A.

supporting information, p. 576 - 581 (2014/06/09)

The emergence and spread of malaria parasites that are resistant to chloroquine (CQ) has been a disaster for world health. The antihistamine chlorpheniramine (CP) partially resensitizes CQ-resistant (CQR) parasites to CQ but possesses little intrinsic antiplasmodial activity. Mutations in the parasite's CQ resistance transporter (PfCRT) confer resistance to CQ by enabling the protein to transport the drug away from its site of action, and it is thought that resistance-reversers such as CP exert their effect by blocking this CQ transport activity. Here, a series of new structural analogues and homologues of CP have been synthesized. We show that these compounds (along with other in vitro CQ resistance-reversers) inhibit the transport of CQ via a resistance-conferring form of PfCRT expressed in Xenopus laevis oocytes. Furthermore, the level of PfCRT-inhibition was found to correlate well with both the restoration of CQ accumulation and the level of CQ resensitization in CQR parasites.

Polymorphic forms of olopatadine hydrochloride and methods for producing olopatadine and salts thereof

-

Page/Page column 24-25, (2008/06/13)

The present invention provides a novel polymorphic form of olopatadine hydrochloride ([(Z)-3-(dimethylamino)propylidene]-6,11-dihydrodibenz[b,e]oxepin-2-acetic acid hydrochloride), a selective histamine H1-receptor antagonist that is used for the treatment of ocular symptoms of seasonal allergic conjunctivitis. The present invention also provides novel methods for producing olopatadine on a large scale, and in a manner that is cost effective, provides a low level of impurities and eliminates the need to use the costly and dangerous base, butyllithium, which is used in prior art reactions for making olopatadine. The present invention further provides novel processes for carrying out a large scale production of 3-dimethylaminopropyltriphenylphosphonium bromide and its corresponding hydrobromide salt, which are employed in the production of olopatadine, and pharmaceutically acceptable salts of olopatadine.

Discovery of diphenyl amine based sodium channel blockers, effective against hNav1.2

Hudgens, Debjani P.,Taylor, Catherine,Batts, Timothy W.,Patel, Manoj K.,Brown, Milton L.

, p. 8366 - 8378 (2008/02/05)

The development of new therapies for chronic pain is an area of unmet medical need. Central to pathways of chronic pain is the upregulation of voltage-gated sodium channels. The use of tricyclic antidepressants, which also have sodium channel activity, in chronic pain therapy prompted us to develop novel compounds from this scaffold. Herein, we show that the tricyclic moiety is not needed for effective inhibition of the [3H]-BTX binding site and sodium currents of hNav1.2. Our lead compound 6, containing a diphenyl amine motif, demonstrated a 53% inhibitory block of Nav1.2 currents at 10 μM, which is greater than 50% increase in current block in comparison to the amitriptyline standard. Altogether our study establishes that the tricyclic motif is unnecessary for hNav1.2 activity and modification of the amine portion is detrimental to sodium channel block.
