1. Methylated amino acids and lysosomal function in cultured heart cells
R S Decker, J F Fuseler Exp Cell Res. 1984 Sep;154(1):304-9. doi: 10.1016/0014-4827(84)90690-6.
Methylated amino acids inhibit lysosomal function in cultured rat heart myocytes more effectively than the classically employed lysosomotropic weak bases. Moreover, L-leucine methyl ester (L-Leu-OMe) or L-methionine methyl ester (L-Meth-OMe) do not alter lysosomal pH or inactivate lysosomal cysteine proteinases, but do inhibit protein degradation more efficiently than either chloroquine or NH4Cl. These observations suggest that amino acid methyl esters are more effective probes to investigate lysosomal function in cultured myocytes than chloroquine or NH4Cl.
2. Non-glutamate type pyrrolo[2,3-d]pyrimidine antifolates. II. Synthesis and antitumor activity of N5-substituted glutamine analogs
F Itoh, Y Yoshioka, K Yukishige, S Yoshida, M Wajima, K Ootsu, H Akimoto Chem Pharm Bull (Tokyo). 1996 Aug;44(8):1498-509. doi: 10.1248/cpb.44.1498.
The glutamic acid moiety of N-[4-[3-(2,4-diamino-7H-pyrrolo[2, 3-d]pyrimidin-5-yl)propyl]benzoyl]-L-glutamic acid (1b, TNP-351) and related compounds was replaced with some N5-substituted glutamines. Antifolates (4A-S) were effectively prepared by coupling pyrrolo[2,3-d]pyrimidine carboxylic acids (11a, b) with some properly protected N5-substituted glutamine derivatives (10A-S), which were prepared by coupling Boc-Glu-OMe (7) with various amines (8A-S) using a suitable condensing reagent, followed by hydrolysis. The inhibitory effects of the resulting products on dihydrofolate reductase (DHFR), thymidylate synthetase (TS) and the growth of murine fibrosarcoma Meth A cells in culture were examined. All N5-substituted glutamine analogs (4A-S) inhibited DHFR much more strongly than TNP-351 and some analogs exhibited the same potent growth inhibition of Meth A cells as TNP-351. Some typical analogs (4Bb, 4Db, 4F, 4Oa) were also examined for inhibitory effects on the growth of methotrexate (MTX)-resistant human CCRF-CEM cells in culture and for in vivo antitumor activities against murine leukemia and solid tumors. MTX-resistant cells, with a defect in transport and decreased polyglutamylation activity, showed little cross resistance to the analog (4Oa) having a tetrazole moiety as a substituent of glutamine, which exhibited potent antitumor activities. These results demonstrate that the antifolate analogs (4) with N5-substituted glutamine in place of glutamic acid are novel potent DHFR inhibitors with activity against MTX-resistant tumors. The potent antitumor activity of these analogs (4) may result from their effective uptake via reduced folate carrier in combination with their potent inhibition of DHFR.
