Various chemical treatments were evaluated over two growing seasons for control of triazine-resistant common lambsquarters (Chenopodium albumL. # CHEAL) and for control of a triazine-resistant infestation containing both redroot pigweed (Amaranthus retroflexusL. # AMARE) and Powell amaranth (A. powelliiS.

Abstract:

The cross-resistance of triazine-resistant biotypes of smooth pigweed (Amaranthus hybridusL. # AMACH), common lambsquarters (Chenopodium albumL. # CHEAL), common groundsel (Senecio vulgarisL. # SENVU), and the crop canola (Brassica napusL. var. Atratower) to a selection of herbicides was evaluated at both the whole plant and chloroplast level. The triazine-resistant biotypes of all four species showed a similar pattern of cross-resistance, suggesting that a similar mutation had occurred in each species.

Seasonal residues of an acetanilide and triazine herbicide were monitored in ridge, conventional, and zero tillage systems.

Moldboard plowing in the fall reduced herbicide residues in spring because of soil dilution by plowing to greater than the sampling depth. Ridge tillage systems had higher spring residues apparently because of reduced herbicide dissipation on

The dihedral angle between the planes of the triazine and benzene rings is 4.04 (8)°. In the crystal, two weak C—H...N hydrogen bonds and short Cl...Cl contacts [3.4222 (4) Å] link adjacent molecules, forming two-dimensional networks parellel to the (112) plane. The planes are linked by weak intermolecular π–π interactions [3.6428 (5) and 3.6490 (5) Å], resulting in a three-dimensional architecture.

Abstract:

Abstract Derivatives of 6-chloro-5-methylthiopyrimidines provide potent inhibitors of the photosynthetic electron flow, which act like Diuron on fluorescence induction kinetics and competitively displace it from its binding site. Structure-activity relationships show that, unlike triazines, activities of 2-or 4-alkylamino derivatives are restricted by steric hindrances. Decreases in inhibitory activities of these compounds observed in triazine-resistant chloroplasts are lower than decreases reported for triazines themselves.

Among serotonin receptors, the 5-HT6 subtype is the most controversial and the least known in the field of molecular mechanisms. The 5-HT6R ligands can be pivotal for innovative treatment of cognitive impairment, but none has reached pharmacological market, predominantly, due to insufficient “druglikeness” properties. Recently, 1,3,5-triazine-piperazine derivatives were identified as a new chemical family of potent 5-HT6R ligands.

Abstract:

A convenient synthetic approach to meso-substituted with 2,2’-bipyridine and 1-(pyridin-2-yl)isoquinoline residues calix[4]arenes is reported. This approach involves the reaction of generated in situ 2-lithio-calix[4]arene with 1,2,4-triazine precursor with the following aromatization of the obtained adduct, and the aza-Diels-Alder reaction of the 1,2,4-triazinyl-substituted calix[4]arene with 2,5-norbornadien or in-situ generated 1,2-dehydrobenzene. The UV/fluorescence response of thus obtained meso-pyridyl-substituted calix[4]arenes to metal cations is studied.
