Tissue-specific expression from a compound TATA-dependent and TATA-independent promoter [PDF]

, 1990
We have found that the mouse metallothionein-I (MT-I) gene promoter functions in an unusual, compound manner. It directs both TATA-dependent and TATA-independent modes of transcription in vivo.

Trimethoprim: An Old Antibacterial Drug as a Template to Search for New Targets. Synthesis, Biological Activity and Molecular Modeling Study of Novel Trimethoprim Analogs

Molecules, 2019
A new series of trimethoprim (TMP) analogs containing amide bonds (1−6) have been synthesized. Molecular docking, as well as dihydrofolate reductase (DHFR) inhibition assay were used to confirm their affinity to bind dihydrofolate reductase enzyme.

Tetrahydrobiopterin Uptake in Supplemental Administration: Elevation of Tissue Tetrahydrobiopterin in Mice Following Uptake of the Exogenously Oxidized Product 7,8-Dihydrobiopterin and Subsequent Reduction by an Anti-folate-Sensitive Process

Journal of Pharmacological Sciences, 2004
In order to increase the tissue level of tetrahydrobiopterin (BH4), supplementation with 6R-tetrahydrobiopterin (6RBH4) has been widely employed. In this work, the effectiveness of 6RBH4 was compared with 7,8-dihydrobiopterin (7,8BH2) and sepiapterin by ...
