Summary for Patent: 4,263,293
Title: Heterocyclic containing amides as inhibitors of mammalian collagenase
Abstract:Mammalian collagenase is inhibited by compounds having the formula ##STR1## wherein R.sub.1 is hydrogen, alkanoyl of 2 to 10 carbon atoms or arylcarbonyl; R.sub.2 is 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, 1-piperazinyl, or 4-alkyl-1-piperazinyl; R.sub.3 is alkyl of 3 to 8 carbon atoms, cycloalkyl, aryl, or arylalkyl; and n is an integer of 1 to 20.
Inventor(s): Sundeen; Joseph E. (Yardley, PA), Dejneka; Tamara (Skillman, NJ)
Assignee: E. R. Squibb & Sons, Inc. (Princeton, NJ)
Application Number:06/154,748
Patent Claims:1. A compound having the formula ##STR14## wherein R.sub.1 is hydrogen, alkanoyl of 2 to 10 carbon atoms or arylcarbonyl;

R.sub.2 is 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, 1-piperazinyl, or 4-alkyl-1-piperazinyl;

R.sub.3 is alkyl of 3 to 8 carbon atoms, cycloalkyl, aryl, or arylalkyl; and

n is an integer of 1 to 20.

2. A compound in accordance with claim 1 wherein R.sub.3 is 2-methylpropyl.

3. A compound in accordance with claim 1 wherein R.sub.1 is hydrogen, acetyl or benzoyl.

4. A compound in accordance with claim 1 wherein n is an integer of 2, 3 or 4.

5. The compound in accordance with claim 1 (.+-.)-2-[(acetylthio)methyl]-4-methyl-N-[2-(4-morpholinyl)ethyl]pentanami de.

6. The compound in accordance with claim 1 (.+-.)-2-[(acetylthio)methyl]-4-methyl-N-[2-(1-piperidinyl)ethyl]pentanami de.

7. The compound in accordance with claim 1 2-(mercaptomethyl)-4-methyl-N-[2-(4-morpholinyl)ethyl]pentanamide.

8. The compound in accordance with claim 1 2-(mercaptomethyl)-4-methyl-N-[2-(1-piperidinyl)ethyl]pentanamide.

9. A method for reducing the adverse effects of mammalian collagenase in a mammal host in need thereof, which comprises administering to said mammal an effective amount of a compound having the formula ##STR15## wherein R.sub.1 is hydrogen, alkanoyl of 2 to 10 carbon atoms or arylcarbonyl;

R.sub.2 is 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, 1-piperazinyl, or 4-alkyl-1-piperazinyl;

R.sub.3 is alkyl of 3 to 8 carbon atoms, cycloalkyl, aryl, or arylalkyl; and

n is an integer of 1 to 20.
