The tert-butyl group is a common motif in medicinal chemistry. Its incorporation into bioactive compounds is often accompanied by unwanted property modulation, such as increased lipophilicity and decreased metabolic stability. Several alternative substituents are available for the drug discovery process.

Oligonucleotides modified by clinically ineffective trans-diamminedichloridoplatinum(II) (transplatin) have been shown to be effective modulators of gene expression. This is so because in some nucleotide sequences the 1,3-GNG intrastrand adducts formed by transplatin in double-helical DNA readily rearrange into interstrand cross-links
