Patent ID: 7834174

Claim:
Compounds of type per(6-deoxy-6-substituted)-cyclodextrins consisting of: hexakis(6-deoxy-6-NH(CH 2 ) n —R 1 )-α-cyclodextrin, wherein (a) R 1 equals NH 2 (amino group) and n equals 3 or 4 or 5 or 6; or (b) R 1 equals C(═NH)NH 2 and n equals zero; or (c) R 1 equals NHC(═NH)NH 2 (guanidino group) and n equals 2 or 3 or 4 or 5 or 6; and heptakis(6-deoxy-6-NH(CH 2 ) n —R 1 )-β-cyclodextrin, wherein (d) R 1 equals NH 2 (amino group) and n equals 3 or 4 or 5 or 6; or (e) R 1 equals C(═NH)NH 2 and n equals zero; or (f) R 1 equals NHC(═NH)NH 2 (guanidino group) and n equals 2 or 3 or 4 or 5 or 6; and octakis(6-deoxy-6-NH(CH 2 ) n —R 1 )-γ-cyclodextrin, wherein (g) R 1 equals NH 2 (amino group) and n equals 2 or 3 or 4 or 5 or 6; or (h) R 1 equals C(═NH) NH 2 and n equals zero; or (i) R 1 equals NHC(═NH)NH 2 (guanidino group) and n equals 2 or 3 or 4 or 5 or 6.
