International journal of peptides, 2013, 197317-197317 (2013-09-13)
Unified schedule for multiple parallel solid-phase synthesis of so-called "difficult" peptides on polypropylene pins was developed. Increase in the efficiency of 9-fluorenyl(methoxycarbonyl) N-terminal amino-protecting group removal was shown to have a greater influence on the accuracy of the "difficult" peptide

Molecules (Basel, Switzerland), 26(5) (2021-04-04)
In the present work, the thermochemistry of solution, solvation, and hydrogen bonding of cyclic amides in proton acceptor (B) and proton donor (RXH) solvents were studied. The infinite dilution solution enthalpies of δ-valerolactam, N-methylvalerolactam, ε-caprolactam, and N-methylcaprolactam were measured at
