| pubmed-article:7057421 | pubmed:abstractText | Forty-five 4,6-diamino-1,2-dihydro-2,2-dimethyl-1-(3-X-phenyl)-s-triazine inhibitors of dihydrofolate reductase (DHFR) and methotrexate (MTX) were tested on L5178Y/R murine tumor cell culture. The concentration of inhibitor causing a 50% decrease in growth rate was determined, and from these results a quantitative structure-activity relationship (QSAR) was developed. This QSAR is compared with QSAR for the same inhibitors acting on isolated DHFR and on L5178Y cell culture sensitive to MTX. The results show that very potent triazine inhibitors of resistant tumor cell growth can easily be made by making the triazines strongly hydrophobic. The optimum pi value for inhibition of MTX-sensitive cell culture is 0.8, while pi 0 for the resistant cell culture is about 6.0. The QSAR for MTX-sensitive and -resistant tumor cell culture inhibition is compared with the corresponding QSAR for Lactobacillus casei cells. Both the mammalian and bacterial cells appear to protect themselves from the highly hydrophilic MTX by erecting lipophilic barriers. | lld:pubmed |
