4 Drug and Medication Information
4.1 Therapeutic Uses

EXPTL USE: ADMIN OF LYSYL OXIDASE INHIBITOR, BAPN, PREVENTED DEVELOPMENT OF HYPERTENSION & DECR AMT OF VASCULAR COLLAGEN IN RATS IN WHICH HYPERTENSION HAD BEEN INDUCED. HISTOLOGICAL EXAM REVEALED THAT ARTERIOSCLEROTIC CHANGES WERE PREVENTED BY BAPN.

PMID:909131 OOSHIMA A; JPN CIRC J 41(8): 912 (1977)


EXPTL USE: IN YOUNG HYPERTENSIVE RATS, BAPN (20 MG, IP DAILY, FOR 2 WK) PREVENTED DEVELOPMENT OF HYPERTENSION. IN ADULT SPONTANEOUS HYPERTENSIVE RATS (50 MG, IP, DAILY FOR 2 WK) DECR BLOOD PRESSURE.

PMID:723006 OGAWA M, OZAKI M; JPN J PHARMACOL 28(5): 785 (1978)


EXPTL USE: RATS WITH SC IMPLANTED POLYVINYL ALCOHOL SPONGES AND WITH INFLICTED SKIN INCISION WOUNDS RECEIVED A SINGLE INJECTION OF BETA-AMINOPROPIONITRILE (BAPN) AT 4 DOSAGES RANGING FROM 1-40 MG/100 G. EVEN THE LOWEST DOSE OF BAPN INHIBITED LYSYL OXIDASE ACTIVITY FOR 6 HOURS; WITH LARGER DOSAGES THE INHIBITION LASTED LONGER, AT 40 MG BAPN, AT LEAST 48 HOURS. THE MAGNITUDE AND DURATION OF INHIBITION WERE REFLECTED IN THE EXTRACTABILITY OF COLLAGEN AND BURSTING STRENGTH OF THE WOUND. THE DATA SUGGEST THAT A MINIMAL DOSE OF BAPN WOULD BE CLINICALLY EFFECTIVE IF EITHER THE METABOLISM OF THE DRUG WERE REDUCED (BY MONOAMINE OXIDASE INHIBITORS) OR A SUSTAINED-RELEASE PREPARATION OF BAPN WERE USED.

PMID:39201 AREM AJ ET AL; J SURG RES 27(4): 228 (1979)


EXPTL USE: BETA-AMINOPROPIONITRILE (BAPN) WAS TESTED FOR ABILITY TO PREVENT EXCESS COLLAGEN FORMATION IN BLEOMYCIN-INDUCED PULMONARY FIBROSIS IN THE HAMSTER. TWO GROUPS RECEIVED 1 ENDOTRACHEAL DOSE OF BLEOMYCIN; ONE OF THESE WAS INJECTED WITH BAPN TWICE DAILY FOR 30 DAYS. A 3RD GROUP RECEIVED SALINE AND BAPN. THE BLEOMYCIN INCREASED COLLAGEN CONTENT, DECREASED LUNG VOLUME, AND PRODUCED FIBROSIS AND A MORTALITY RATE OF 51%. ADMINISTRATION OF BAPN TO BLEOMYCIN-TREATED ANIMALS PREVENTED EXCESS COLLAGEN ACCUMULATION, PRODUCED LESS FIBROSIS, AND LESSENED MORTALITY RATE TO 24%; BAPN ALONE HAD NO EFFECT ON LUNG MECHANICS OR COLLAGEN CONTENT.

5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

BETA-AMINOPROPIONITRILE (BAPN) WAS FOUND IN URINE WITHIN 1 HR OF ORAL ADMIN. ORAL 250 MG BAPN AT 6 HR INTERVALS EACH DAY FOR 21 DAYS RESULTED IN URINARY BAPN RECOVERIES APPROXIMATING 16% OF TOTAL DOSE. BAPN WAS NOT DETECTED IN SPECIMENS COLLECTED LATER THAN 7 HR AFTER CESSATION OF BAPN DOSAGE. URINARY CYANOACETIC ACID APPEARED MORE SLOWLY THAN BAPN & INCR GRADUALLY TO APPROX 3 TIMES THAT OF URINARY BAPN. AFTER BAPN WAS DISCONTINUED, THERE WAS PROLONGED URINARY EXCRETION OF BAPN-DERIVED CYANOACETIC ACID.

PMID:639425 FLEISHER JH ET AL; CLIN PHARMACOL THER 23(5): 520 (1978)


AFTER APPLICATION TO THE SKIN OF RATS, (14)C-BAPN FREE BASE WAS ABSORBED MORE RAPIDLY AND TO A GREATER EXTENT THAN THE FUMARATE SALT. SIX HOURS AFTER TOPICAL ADMINISTRATION OF THE FREE BASE ONLY TRACES OF (14)C WERE FOUND ON THE SKIN AND LESS THAN 1% OF THE DOSE WITHIN THE SKIN SECTION SUGGESTING RAPID DRUG ABSORPTION.

5.3 Mechanism of Action

The mechanism of the effect is unknown, but it is thought to be by some action on growth of certain mesodermal tissues. It is not due to one of its major metabolites, cyanoacetic acid, and both the free amino group and the cyano group seem essential for activity. It is not produced if the amino group is in the alpha position, or if in the gamma position in butyronitrile.

IT HAS BEEN SUGGESTED THAT LATHYROGENIC AGENTS ACT BY BLOCKING CERTAIN CARBONYL GROUPS NORMALLY PRESENT IN COLLAGEN, & THUS INTERFERING WITH FORMATION OF CROSS LINKAGES. THEIR ACTION MAY BE RETARDED BY RESERPINE OR BY CALCIUM SALTS. /LATHYROGENIC AGENTS/
