On September 4, 1997, Jeon, Yoon T.; Gluchowski, Charles published a patent.SDS of cas: 70202-00-5 The title of the patent was Preparation of novel indoles and benzothiazoles for cloned human alpha 2 receptors. And the patent contained the following:
The title compounds [I-IV; R1-R3 = H, C1-7 alkyl, C2-7 alkenyl, alkynyl; R4-R6 = H, halo, Oh, etc.; R7 = H, NH, C1-7 alkyl, etc.; R8 = H, C1-7 alkyl, C2-7 alkenyl, etc.; R9 = H, Ph, C1-7 alkyl, etc.; X = CH2, O, NH, S] which are selective for cloned human alpha 2 receptors and therefore useful for lowering intraocular pressure, for treating presbyopia, migraine, hypertension, alc. withdrawal, drug addiction, rheumatoid arthritis, ischemic pain, spasticity, diarrhea, nasal congestion, urinary incontinence as well as for use as analgesics, sedatives, anesthetics, cognition enhancers and ocular vasoconstriction agents, were prepared Thus, reaction of 7-bromo-5-aminoindole with 2-imidazoline-2-sulfonic acid (ISA) afforded 46% I [R1-R5 = H; R6 = Br; R7-R9 = H; X = N] which showed pEC50 of 9.36 at alpha 2 receptor. The experimental process involved the reaction of 7-chloro-benzothiazol-6-ylamine(cas: 70202-00-5).SDS of cas: 70202-00-5
