Disclosed herein are switches for regulating the activity of a chimeric antigen receptor effector cells (CAR-ECs). The switches generally comprise a chimeric antigen receptor-interacting domain (CAR-ID) and a target interacting domain TID. The switch may further comprise a linker. Further disclosed herein are methods of using the switches for the treatment of one or more conditions or diseases in a subject in need thereof.

A general and efficient synthesis of dihydroquinoxalinones has been developed. The reductive cyclization of N‐(o‐nitroaryl)amino esters was performed by using iron and zinc metal under mild conditions in a water/ethyl acetate mixture. The final products were obtained in moderate to high yields and high enantiomeric purity.
Inter- and intramolecular Mitsunobu reaction and metal complexation study: synthesis of S-amino acids derived chiral 1,2,3,4-tetrahydroquinoxaline, benzo-annulated [9]-N3 peraza, [12]-N4 peraza-macrocycles

Substituted 1,2,3,4-tetrahydroquinoxaline, benzo-annulated unsymmetrical chiral [9]-N3 peraza, and [12]-N4 peraza-macrocycles have been synthesized employing an inter- and intramolecular Mitsunobu reaction from an amino acid derived common synthetic intermediate 3. The metal complexation study of these macrocycles has been investigated by UV-visible spectroscopic technique with binding constant (Kb) value 1.84 × 103 dm3 mol−1 using the Benesi–Hildebrand equation and a Gibbs free energy (ΔG) −19.4 kJ mol−1 at 35 °C for 14d with Co2+. The binding properties of the metal were dependent on the structure of polyaza-macrocycles that were confirmed by the DFT optimized structure of two macrocycles. A detailed investigaton of UV-visible spectra of macrocycles and their complete interpretation with the help of TD-DFT along with the frontier molecular orbital calculations are presented.
Unprecedented formation of benzo[d][1,2,3,6]oxatriazocine derivatives via diazo-oxygen bond formation and synthesis of enantiomerically pure 1-alkyl benzotriazole derivatives

A series of amino acid-derived enantiomerically pure substituted benzo[d][1,2,3,6]oxatriazocine derivatives and 1-alkyl substituted benzotriazoles has been prepared by the diazotization of amino acid-derived benzo-fused alicycles. The first unprecedented diazo-oxygen bond formation in acidic medium led to an entirely new kind of substituted benzo[d][1,2,3,6]oxatriazocine heterocycles.
