Pyrrolysine analogs
Several different pyrrolysine analogs are disclosed in this application. Those analogs have distinct chemical and biophysical properties. Some analogs are useful in chemical ligation applications. Methods of making and using are also disclosed.
1. A pyrrolysine analog of Formula (I):
wherein n is from 0 to 8; and Z is a linkage selected from the group consisting of ester, thioester, carbonyl, ether, thioether, carbamate, and amide.
2. The analog of claim 1 , wherein Z is amide, ester, or carbonyl.
3. The pyrrolysine analog of claim 1 , wherein the analog has the structure of Formula (II):
4. The pyrrolysine analog of claim 3 , wherein the analog has the structure of Formula (1):
5. The pyrrolysine analog of claim 3 , wherein the analog has the structure of Formula (2):
6. The pyrrolysine analog of claim 1 , wherein the analog has the structure of Formula (16):
7. A pyrrolysine analog of Formula (XI):
wherein n is from 0to 8;
Z is a linkage selected from the group consisting of ester and amide; and
L is a linkage selected from the group consisting of alkyl and cycloalkyl, either of which may be substituted with one or more substituents selected from the group consisting of alkoxy, halogen, hydroxyl, amino, and thiol.
8. The analog of claim 7 , wherein L is alkyl or substituted alkyl.
9. The analog of claim 7 , wherein L has an amino substituent.
10. A pyrrolysine analog of Formula (IV) or Formula (V):
wherein m is from 1to 6; and
R is selected from the group consisting of alkoxy, halogen, hydroxyl, amino, and thiol.
