Rifalazil (KRM-1648; ABI-1648) is an antibiotic, exhibits high potency against mycobacteria, gram-positive bacteria, Helicobacter pylori, C. pneumoniae and C. trachomatis with MIC values from 0.00025 to 0.0025 μg\/ml. Rifalazil (KRM-1648; ABI-1648) has the potential for the treatment of Chlamydia infection, Clostridium difficile associated diarrhea (CDAD), and tuberculosis (TB).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct information\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 129791-92-0\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 941.07\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormula:\u003c\/strong\u003e C51H64N4O13\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eChemical Name:\u003c\/strong\u003e (7S,11S,12R,13S,14R,15R,16R,17S,18S)-2,6,15,17-tetrahydroxy-11-methoxy-3,7,12,14,16,18,22-heptamethyl-30-[4-(2-methylpropyl)piperazin-1-yl]-23,32,37-trioxo-8,27,38-trioxa-24,34-diazahexacyclo[23.11.1.1⁴,⁷.0⁵,³⁶.0²⁶,³⁵.0²⁸,³³]octatriaconta-1,3,5,9,19,21,25,28,30,33,35-undecaen-13-yl acetate\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSmiles:\u003c\/strong\u003e CC(C)CN1CCN(CC1)C1=CC(=O)C2=NC3C(OC2=C1)=C1NC(=O)C(C)=CC=C[C@H](C)[C@H](O)[C@@H](C)[C@@H](O)[C@@H](C)[C@H](OC(C)=O)[C@H](C)[C@H](C=CO[C@@]2(C)OC4C(=C2O)C=3C(=C(O)C=4C)C1=O)OC |c:29,t:31,51|\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChiKey:\u003c\/strong\u003e IXSVOCGZBUJEPI-MAVZOTGXSA-N\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eInChi:\u003c\/strong\u003e InChI=1S\/C51H64N4O13\/c1-24(2)23-54-16-18-55(19-17-54)32-21-33(57)39-35(22-32)67-48-40(52-39)36-37-44(60)30(8)47-38(36)49(62)51(10,68-47)65-20-15-34(64-11)27(5)46(66-31(9)56)29(7)43(59)28(6)42(58)25(3)13-12-14-26(4)50(63)53-41(48)45(37)61\/h12-15,20-22,24-25,27-29,34,42-43,46,58-60,62H,16-19,23H2,1-11H3,(H,53,63)\/b13-12-,20-15-,26-14-\/t25-,27+,28+,29+,34-,42-,43+,46+,51-\/m0\/s1\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAppearance:\u003c\/strong\u003e Solid Power\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥98% (or refer to the Certificate of Analysis)\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eSolubility:\u003c\/strong\u003e DMSO : 8.33 mg\/mL (8.85 mM; Need ultrasonic).\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShipping Condition:\u003c\/strong\u003e Shipped under ambient temperature as non-hazardous chemical or refer to Certificate of Analysis\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStorage Condition:\u003c\/strong\u003e Dry, dark and -20 \u003csup\u003eo\u003c\/sup\u003eC for 1 year or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eShelf Life:\u003c\/strong\u003e ≥12 months if stored properly.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eStock Solution Storage:\u003c\/strong\u003e 0 - 4 \u003csup\u003eo\u003c\/sup\u003eC for 1 month or refer to the Certificate of Analysis.\u003c\/p\u003e\u003cp style=\"text-indent:-1em;padding-left:1em;\"\u003e\u003cstrong\u003eDrug Formulation:\u003c\/strong\u003e To be determined\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHS Tariff Code:\u003c\/strong\u003e 382200\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to use\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vitro:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003eRifalazil exhibits antimicrobal activity against Gram-positive enteric bacteria, inhibits Clostridium difficile, Clostridium perfringens, Bacteroides fragilis with MIC50 value of 0.0015, 0.0039, 0.0313 µg\/ml, respectively.
