Abstract
Natural killer (NK) cells, in addition to their cytotoxicity function, harbor prominent cytokine production capabilities and contribute to regulating autoimmune responses. T-cell immunoglobulin and mucin domain containing protein-3 (Tim-3) is one of the inhibitory receptors on NK cells and a promising immune checkpoint target. We recently found that phosphatidylserine (PS) binding to Tim-3 can suppress NK cell activation. Therefore, based on the therapeutic potential of Tim-3 in NK-cell-mediated diseases, we developed a photoswitchable ligand of Tim-3, termed photophosphatidylserine (phoPS), that mimics the effects of PS. Upon 365 or 455 nm light irradiation, the isomer of phoPS cyclically conversed the cis/trans configuration, resulting in an active/inactive Tim-3 ligand, thus modulating the function of NK cells in vitro and in vivo. We also demonstrated that reversible phoPS enabled optical control of acute hepatitis. Together, phoPS may be an appealing tool for autoimmune diseases and cytokine storms in the future.

Abstract
![]()
A catalytic enantioselective method
for the synthesis of α-quaternary
Mannich-type products is reported. The two-step sequence of (1) Mannich
reaction followed by (2) decarboxylative enantioselective allylic
alkylation serves as a novel strategy to in effect access asymmetric
Mannich-type products of “thermodynamic” enolates of
substrates possessing additional enolizable positions and acidic protons.
Palladium-catalyzed decarboxylative allylic alkylation enables the
enantioselective synthesis of five-, six-, and seven-membered ketone,
lactam, and other heterocyclic systems. The mild reaction conditions
are notable given the acidic free N–H groups and high functional
group tolerance in each of the substrates. The utility of this method
is highlighted in the first total synthesis of (+)-sibirinine.

Abstract
Cyclic enesulfonamides, enecarbamates, or enamides tethered to an alkyne cyclize readily with use of platinum(II) chloride. This reaction generates quaternary-substituted carbon centers within simple spiro-fused or more complex tri- and tetracyclic heterocyclic ring systems. The yields for this process range from 50% to 83%. [reaction: see text].
