Summary: The fine structure of plastids and the carotenoid content
of ripening pepper fruits were studied. Red ripe fruits contained
spindle-shaped chromoplasts which originated from leuco-chloroplasts. The
bleaching herbicides amitrole and SAN 9789 inhibited the biosynthesis of
total carotenoids and the development of typical spindle-shaped
chromoplasts. Both herbicides prevented the formation of tubules and
increased the accumulation of plastoglobules.

Summary: The roots of some vascular plants become green when kept in
the light. Chloroplasts first appeared in the oldest root zones, in the
innermost parenchyma. The greening then gradually spread into more
peripheral cell layers and into younger root segments. The number of
photosynthetically active chloroplasts increased, during the greening
process.

Summary: The biological properties of the plant hormone
(auxin)indol-3-ylacetic acid (IAA) and its ring-substituted derivativeshave
so far been rationalized by hypotheses based on incompletestructural data.
Here we compare the molecular structures of IAAand
5-(n-alkyl)indol-3-ylacetic acid (alkyl = methyl, ethyl,propyl, butyl), as
revealed by X-ray crystallography andmolecular mechanics calculations, and
their growth-promotingactivity in the Avena mesocotyl test. For the
compounds studiedthe 5-(n-alkyl) residue was in an extended zig-zag
conformationwith the C-alpha - C-beta bond perpendicular to, and the C-beta
-C-gamma bond pointing away from the aromatic nucleus. In thecrystalline
state, the methylene-carboxyl bond was perpendicularto the indole ring
plane for 5-methylindole-3-ylacetic acid, andapproximately in that plane
for the other IAA derivativesstudied. Crystal packing influences appear to
be responsible forthis effect, as indicated by the results of molecular
mechanicscalculations. In the potential energy-minimized conformation
forthe isolated molecules in the gas phase, perpendicularorientation for
the carboxyl group was always predominant. Theplant growth-promoting
properties of the compounds studied werenot dramatically different. This
indicates that a 5-substituentas bulky as n-butyl, in the orientation
detailed above, does notsterically obstruct interaction with the
auxin-binding protein(s)involved in the growth response.

Summary: The importance of 6-(F-18)fluoro-L-DOPA (6-FDOPA) for
probingthe central dopamine metabolism in vivo in humans using
positronemission tomography (PET) has promoted considerable interest inits
synthesis. We report a new method for the synthesis of6-FDOPA and other
fluorinated analogs of L-DOPA based on aregioselective
radiofluorodestannylation procedure usingelementary F-18 and (F-18) acetyl
hypofluorite. We have preparedfor the first
timeN-formyl-3,4-di-t-butoxycarbonyloxy-6-(trimethylstannyl)-L-phenylalanin
e ethyl ester (1) as an ideal precursor of 6-FDOPA, whichefficiently and
directly reacts with elementary F-18. Theregioselective
radiofluorodestannylation of 1 with F-18 and(F-18) acetyl hypofluorite
afforded, after acidic hydrolysis,6-FDOPA with a radiochemical yield of 25%
(theoretical maximum:50%), ready for human use. Similarly, 6-(F-18) and
4-(F-18)fluoro-L-m-tyrosine (6-FMT and 4-FMT) were synthesized from
thecorresponding 6- and 4-trimethylstannyl-L-m-tyrosine derivativesin 23
and 11% radiochemical yields, respectively.
Likewise,4-(F-18)fluoro-beta-fluoromethylene-m-tyrosine (4-FMFMT), aprobe
for monoamine oxidase in dopaminergic terminals, wassynthesized from the
corresponding 4-trimethylstannylbeta-fluoromethylene m-tyrosine derivative
in 7% radiochemicalyield. The procedure can also be extended to the
synthesis offluoromethyl-4-(or 6-) (F-18)fluoroarylalanine derivatives
thatmay be used as probes for aromatic amino acid decarboxylase basedon
suicide enzyme inhibition mechanisms.

Summary: 6-(F-18)-Fluoro-L-DOPA (FDOPA), a functional analog of
exogenousL-DOPA is useful to determine in-vivo aromatic amino
aciddecarboxylase (AAAD) mediated decarboxylation and apparentdopamine
turnover rates. Also, 4- (4-FMT) and6-(F-18)fluoro-L-m-tyrosines (6-FMT)
are analogs that essentiallyfollow the L-DOPA pathway of central
metabolism, without3-O-methylation or extensive peripheral
metabolism.Interestingly, molecular and enzymatic mechanisms involved
intheir retention in central brain structures differ substantially.In
addition, radiofluorinated enzyme probes based on theprinciple of
dual-enzyme (AAAD-MAO) inhibition will be discussedwith respect to the
influence of stereo- and geometric isomerismson the enzymatic behavior and
central kinetics in primates.Finally, analogs that bind selectively and
covalently to AAAD(e.g. alpha-fluoromethyl-6-(F-18)fluoro-L-DOPA) will
beintroduced. All these analogs will be presented in a context of auseful
strategy for designing radiotracers to probe specificenzymes and their
functions.

Summary: We have investigated the stereo (D,L) and geometric
(E,Z)specificity of radiofluorinated beta-fluoromethylene-m-tyrosine(FMFMT)
derivatives as probes for the central dopaminergic systemwith positron
emission tomography. The individual6-radiofluorinated enantiomers: L- E ,
D- E , and the D,L- Z andD,L- E isomers were prepared by direct
radiofluorination, with(F-18)acetylhypofluorite, of the corresponding
precursors andpurified by preparative C-18 reverse phase HPLC.
Macacanemestrina monkeys (with carbidopa (CD), 5 mg/kg; n = 6 andwithout
CD; n= 2) were injected IV with the purifiedradiofluorinated isomers (see
above) (5 - 12 mCi) and thedistribution of activity followed in central
brain structures.The L- E FMFMT isomer was the only one showing specific
striatallocalization of activity (striatum:cerebellum ratio:
3.00+-0.43(w/CD); 4.25+-0.35 (wo/CD) at 2h). FMFMT tissue-time activitydata
(Patlak) showed essentially irreversible metabolic trappingof the activity
in dopaminergic structures: L- E FMFMT:Distribution volume (Dv) = 1,0; K3 =
0.0067 +-0.0018 (n = 4);D,L- E FMFMT; Dv = 0.5; 0.0034+-0.0008 (n=2).
Neither the D- Estereomer nor the L- Z (or D- Z ) geometric isomers showed
anysignifficant in vivo striatal localization probably due to
theirrestricted BBB permeability. L E FMFMT arterial plasmametabolites also
have poor BBB permeability. The striatalbehavior of L- E FMFMT is
consistent with its aromatic amino aciddecarboxylase mediated
decarboxylation. This combined with itslow peripheral metabolism (10%
metabolites w/CD and 20% wo/CD upto 2h) makes it a valuable PET tracer for
assessment of centraldopaminergic mechanisms.

Summary: Pea (Pisum sativum L.) fruits contain the auxins
indole-3-acetic acid (IAA) and 4-chloroindole-3-acetic acid (4-Cl-IAA). To
understand the effect of the halogen on biological activity, IAA and its
analogues substituted with chlorine or fluorine in ring positions 4, 5, 6,
or 7 were applied to deseeded pea fruits. While 4-Cl-IAA sustained almost
normal growth, the other halogenated compounds were less effective. With
IAA, and in controls without auxin, the deseeded fruits did not grow and
abscised.

Summary: Deseeding pea (Pisum sativum L.) fruits arrests the growth
of the pericarp, followed by its abscission. Application of auxins or
gibberellins partially reverses the effect of seed removal. 4-Cl-IAA, an
endogenous auxin of peas, is uniquely active. One of its effects appears to
be a stimulation of the oxidation of GA-19 to GA-20, a significant step in
the biogenesis of bioactive gibberellins.

Summary: As a part of molecular recognition studies on auxins, a
series of indole-3-acetic acids (IAAs) fluorinated at ring-positions 4, 5,
6 or 7 was examined by X-ray crystallography and by molecular mechanics and
dynamics simulations. No major conformational differences were detected.
The growth-promoting properties of IAA and its fluorinated analogues in the
Avena coleoptile straight-growth test were nearly the same, except for
4-F-IAA which was about 10 times more active.

Summary: Plastid ultrastructure and carotenoid content of pepper
(Capsicum annuum L.) fruits was studied, along with the changes caused by
the herbicides SAN 9789 and amitrole. During ripening, the
leuco-chloroplasts of the young fruit transformed into spidle-shaped
chromoplasts filled with numerous tubules and plastoglobules.
Simultaneously, the chlorophyll disappeared, and carotenoid levels
increased. The two herbicides inhibited carotenoid synthesis and typical
chromoplast development, but stimulated the formation of plastoglobules.

Summary: Racemic beta-fluoromethylene-m-tyrosine (FMMT) is used as
an aromatic amino acid decarboxylase-activated monoamine oxidase inhibitor.
We separated the geometric and optical isomers and introduced F-18 at
specific positions of the aromatic nucleus. In vivo striatal localization,
as shown by positron emission tomography (PET), decreased in the order:
6F-S-(E)-FMMT > 2F-S(E)-FMMT > 4F-R,S-(E)-FMMT, and was undetetable for
radiofluorinated analogs of R-(E)-FMMT and R,S-(Z)-FMMT.
