Abstract:
Epichloë species and their anamorphs, Neotyphodium species, are fungal endophytes that inhabit cool-season grasses and often produce bioprotective alkaloids. These alkaloids include lolines, which are insecticidal and insect feeding deterrents. Lolines are exo-1-aminopyrrolizidines with an oxygen bridge between carbons 2 and 7, and are usually methylated and formylated or acetylated on the 1-amine. In previously published studies lolines were shown to be derived from the amino acids L-proline and L-homoserine. In addition the gene cluster involved in loline-alkaloid biosynthesis has also been

Abstract:
Lolines are specialized metabolites produced by endophytic fungi, such as Neotyphodium and Epichloë species, that are in symbiotic relationships with cool-season grasses. Lolines are vital for the survival of the grasses because their insecticidal and antifeedant properties protect the plant from insect herbivory. Although lolines have various bioactivities, they do not have any concomitant antimammalian activities. Lolines have complex structures that are unique among naturally occurring pyrrolizidine alkaloids. Lolines have four contiguous stereocenters, and they contain an ether bridge conn

Abstract:
Pyrrolizidine alkaloids are cytotoxic, carcinogenic, and anti-carcinogenic in vivo and in vitro, and they produce many hazardous effects in humans and animals. Pyrrolizidine alkaloids (PAs) also cross-link with DNA and/or protein. However, whether such cross-linking is important to the toxic action of PAs is not known. In addition, the exact mechanism underlying these DNA cross-links or cytotoxicity is also not clear. In three separate studies, I characterized the nature of PA-induced DNA cross-links and the relationships between PA structures and cross-linking potency. In the first study (Cha

Abstract:
In humans, livestock and experimental animals, pyrrolizidine alkaloids (PAs) are toxic as a consequence of their hepatic metabolism to reactive pyrrolic esters, or dehydroalkaloids (DHAs). Despite their similarity in structures, PAs often vary markedly in their lethality (LD₅₀s) and in the organs in which toxicity is expressed. We have examined whether there are differences in the physicochemical properties of certain DHAs which are associated with differences in patterns of metabolism and toxicity produced by the parent PA.

Abstract:
Pyrrolizidine alkaloids are proposed to be metabolized in the liver to reactive pyrrole species, or dehydroalkaloids. These reactive pyrroles are hypothesized to be responsible for pyrrolizidine alkaloid toxicity. This dissertation research has established that dehydroalkaloids are, in fact, metabolites of pyrrolizidine alkaloids. It was first determined that dehydromonocrotaline is produced during hepatic microsomal metabolism of monocrotaline and that it has the ability to bind in vitro with a synthetic thiol-containing resin, Thiopropyl Sepharose 6B.

Pyrrolizidine alkaloids (PAs) are natural plant compounds found in hundreds of plant species worldwide and are reported to have cytotoxic, carcinogenic, antimitotic, and gentotoxic activity. PAs are metabolized by the cytochrome P450 (CYP) sytem to the pyrrole or the N-oxide form. They pyrroles are bifunctional electrophillic alkylators that bind cellular nucleophiles such as DNA and proteins and disrupt normal cell processes, including DNA replication and gene transcription, and can cause megalocytosis.
