摘要:
Methods of identifying ligand binding sites in a target molecule such as a polynucleotide or polypeptide, as well as methods for determining whether a particular site in a target molecule is at or near the ligand binding site, are provided. Ligand binding affinities corresponding to both the target molecule and a modified version thereof are compared, preferably using mass spectral analysis. The modified molecules, or test molecules, incorporate a modification capable of modulating ligand binding affinity when located at or near the ligand binding sites. Binding site information is derived from the known position of the modification.

Provided are compounds of the formula: wherein RN1 is a substituent of formula G1-NX1X2, wherein G1 is an optionally further substituted alkylene, which optionally forms, together with RN2, a cyclic group, and each of X1 and X2 is independently H or an N-substituent, or X1 and X2 together form a heterocyclic ring, or X1 together with G1 forms a cyclic group and X2 is H or an N-substituent; and each of Z1, Z2, Z3 and Z4 is H or a substituent, or two of Z1, Z2, Z3 and Z4 together form an optionally substituted ring, and further wherein at least one of Z1, Z2, Z3 and Z4 is other than H, and salts thereof, pharmaceutical compositions and methods of using the compounds. The compounds have antiviral activity.

摘要:
This invention is directed to novel pyranosyl cytosine compounds depicted graphically as structure I. This invention is further directed to a unique methodology for their preparation using solid-phase methodology. These hexopyranosyl cytosine derived natural product analogs share their parent compounds broad-spectrum antimicrobial and anti-fungal profile and represent a vast, novel compound class of 50S rRNA directed inhibitors of protein translation.
