The present invention generally relates to a chemical process under flow conditions for manufacturing compounds which absorb ultraviolet (UV) radiation and protect biological materials as well as non-biological materials from damaging exposure to UV radiation. The present invention further includes formulations and compositions comprising such compounds for use in absorbing UV radiation, as well as methods for protecting biological materials as well as non-biological materials from damaging exposure to UV radiation.

The inhibitory effect of 108 4,6-diamino-1,2-dihydro-2,2-dimethyl-1-(substituted-phenyl)-s-triazines on murine L5178Y tumor cells, resistant and sensitive to methotrexate (MTX), has been studied. From the pI50 values, quantitative structure-activity relationships have been formulated which show that the lipophilic triazines are much more inhibitory against resistant cells than methotrexate or hydrophilic triazines. The results are compared with the behavior of other antifolate drugs that have been used in chemotherapy, as well as with eight antitumor drugs that are not antifolates. The acquired resistance of these cells toward hydrophilic antifolates may be attributed to the combined effect of an impaired active-transport system, a change in the conformation of dihydrofolate reductase in the resistant cells, and an amplified production of dihydrofolate reductase in the resistant cells.

Liquid crystalline lanthanide complexes with N-aryl-substituted beta-aminovinyl ketones were synthesized for the first time. The complexes give rise to smectic A mesophase and are stable only in the solid state; in going to solution, they dissociate with formation of the initial ligand.
