???????,?N,N’,N”,N”’,N””-Pentaacetyl chitopentaoseChitopentaose is a pentaacetyl derivative of the sugar chitohexaose. It is an oligosaccharide that has been shown to inhibit the activity of glycosidases and lectins, which may be due to its high affinity to these enzymes. Chitopentaose has also been found to bind to insulin receptors in the human tumor cell line A-20, leading to a reduction in tumor growth. The molecule also inhibits the transcriptional regulation of genes encoding for penicillin-binding protein, mouse tumor necrosis factor, and ?1-acid glycoprotein.CAS Number36467-68-2Product NameN,N’,N”,N”’,N””-PentaacetylchitopentaoseIUPAC NameN-[(3R,4R,5S,6R)-5-[(2S,3R,4R,5S,6R)-3-acetamido-5-[(2S,3R,4R,5S,6R)-3-acetamido-5-[(2S,3R,4R,5S,6R)-3-acetamido-5-[(2S,3R,4R,5S,6R)-3-acetamido-4,5-dihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-4-hydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-4-hydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-4-hydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-2,4-dihydroxy-6-(hydroxymethyl)oxan-3-yl]acetamideMolecular FormulaC40H67N5O26Molecular Weight1034 g/molInChIInChI=1S/C40H67N5O26/c1-11(51)41-21-28(58)32(17(7-47)63-36(21)62)68-38-23(43-13(3)53)30(60)34(19(9-49)65-38)70-40-25(45-15(5)55)31(61)35(20(10-50)67-40)71-39-24(44-14(4)54)29(59)33(18(8-48)66-39)69-37-22(42-12(2)52)27(57)26(56)16(6-46)64-37/h16-40,46-50,56-62H,6-10H2,1-5H3,(H,41,51)(H,42,52)(H,43,53)(H,44,54)(H,45,55)/t16-,17-,18-,19-,20-,21-,22-,23-,24-,25-,26-,27-,28-,29-,30-,31-,32-,33-,34-,35-,36?,37+,38+,39+,40+/m1/s1InChI KeyBZBKTWJIYTYFBH-YSJWDAEMSA-NSMILESCC(=O)NC1C(C(C(OC1O)CO)OC2C(C(C(C(O2)CO)OC3C(C(C(C(O3)CO)OC4C(C(C(C(O4)CO)OC5C(C(C(C(O5)CO)O)O)NC(=O)C)O)NC(=O)C)O)NC(=O)C)O)NC(=O)C)OSynonymsGlcNAc1-b-4-GlcNAc1-b-4GlcNAc1-b-4GlcNAc1-b-4GlcNAcCanonical SMILESCC(=O)NC1C(C(C(OC1O)CO)OC2C(C(C(C(O2)CO)OC3C(C(C(C(O3)CO)OC4C(C(C(C(O4)CO)OC5C(C(C(C(O5)CO)O)O)NC(=O)C)O)NC(=O)C)O)NC(=O)C)O)NC(=O)C)OIsomeric SMILESCC(=O)N[C@@H]1[C@H]([C@@H]([C@H](O[C@H]1O[C@@H]2[C@H](O[C@H]([C@@H]([C@H]2O)NC(=O)C)O[C@@H]3[C@H](O[C@H]([C@@H]([C@H]3O)NC(=O)C)O[C@@H]4[C@H](O[C@H]([C@@H]([C@H]4O)NC(=O)C)O[C@@H]5[C@H](OC([C@@H]([C@H]5O)NC(=O)C)O)CO)CO)CO)CO)CO)O)O
