Barrenness of the Pampas [PDF]
I AM anxious to add a few further remarks on this interesting subject. It was during its investigation that I was so deeply impressed with the desperate struggle for existence which characterises the bordering fertile zones. I could there watch the contest on the very battle-field itself, and for that purpose I established myself for some months in the

Lenacapavir, the first‐in‐class drug targeting HIV‐1 capsid, is a breakthrough drug in HIV‐1 treatment and prophylaxis. However, a single M66I mutation confers complete viral resistance to lenacapavir. We report herein the design and synthesis of innovative R2 analogs demonstrating low nM potency against HIV‐1 M66I and excellent pharmacokinetics in ...

Backbone Steric Constraints Underlie High Passive Membrane Permeability of N‐Alkyl Peptides
Beyond amide hydrogen removal, steric constraints encoded in N/Cα‐dually substituted backbones are uncovered as a key determinant of passive membrane permeability in N‐alkyl peptides. These constraints restrict conformational freedom and sterically limit backbone hydration during membrane permeation.

The bioavailability of tetracyclines is markedly decreased when co-administered with antacids, milk, or food containing Ca2+. Previously, it was suggested that the effective intestinal permeation of tetracycline (TC) was decreased due to Ca2+ linked ...
