The invention provides compounds of the formula 1
in which
A is a C2- to C4-alkylene group
x is from 1 to 100
R1 is C1-C30-alkyl, C2-C30-alkenyl, C7-C30-alkylaryl
R2 is an aliphatic, cycloaliphatic or aromatic radical which contains at least one structural unit of the formula 2
and
y is from 0 to 100,
with the proviso that y is from 1 to 100 when R2 is of the formula 2, and their use in amounts of from 0.01 to 2% by weight for preventing the formation of gas hydrates in aqueous phases which are in contact with a gaseous, liquid or solid organic phase.
The invention provides a compound of formula:
and methods for making and using the same, where R
1
and R
2
are independently hydrogen, C
1-6
alkyl or C
1-6
haloalkyl; R
3
is hydrogen, halogen, C
1-6
alkyl or C
1-6
alkoxy; R
4
is hydrogen or halogen; and R
5
is a mono- or di-amino acid moiety, a succinic acid moiety, a urea moiety, or a derivative thereof. The invention also provides pharmaceutical compositions comprising a compound of formula I, and methods for making and using the same.

Chemokine receptor antagonists, in particular, 3,7-diazabicyclo[3.3.0]octane compounds according to formula (I) are antagonists of chemokine CCR5 receptors which are useful for treating or preventing an human immunodeficiency virus (HIV) infection, or treating AIDS or ARC. The invention further provides methods for treating diseases that are allieviated with CCR5 antagonists. The invention includes pharmaceutical compositions and methods of using the compounds for the treatment of these diseases. The invention further includes processes for the preparation of compounds according to formula I.
