The synthesis of new and innovative macrocyclic amidinoureas from linear di-Boc-guanidino-alkylamines related to guazatine was accomplished. The macrocyclization reaction proceeds under mild conditions affording 11- to 16-membered rings with a new and previously undescribed structure in good yields. Enantiomericallypure macrocyclic amidinoureas were also synthesised. The strict correlation between

Provided herein are compounds that inhibit pKal, a serine protease whose activity is responsible for proteolytically cleaving kininogen and generating the potent vasodilator and pro-inflammatory peptide bradykinin, which can lead to painful and debilitating inflammatory attacks (e.g., edema). Also provided are pharmaceutical compositions and kits comprising the compounds, and methods of treating pKal-related diseases and disorders (e.g., edema) with the compounds in a subject, by administering the compounds and/or compositions described herein.

Synthetic efforts toward the cytotoxic peptides lucentamycins A−D are described that resulted in the totalsynthesis and biological evaluation of 8-epi-lucentamycin A in 15 steps with 2.2% overall yield. The key epi-nonproteogenic 3-methyl-4-ethylideneproline was synthesized via a titanium-mediated cycloisomerization reaction.
