The present invention relates to immune response modifiers of formula (I), which act selectively through agonism, of Toll-Like Receptors (TLRs), uses thereof, processes for the preparation thereof, intermediates used in the preparation thereof and compositions containing said inhibitors. These inhibitors have utility in a variety of therapeutic areas including the treatment of infectious disease such as Hepatitis (e.g. HCV, HBV), genetically related viral infection and cancer.

Chronic exposure of CARTcells to tumor antigens can lead to CARTcell exhaustion and tumor expansion. To reverse this exhaustion, we have developed two orthogonal strategies to target a potent TLR7 agonist specifically to exhaustedCARTcells. We demonstrate here that both strategies rejuvenate exhaustedCARTcells, leading to dramatic reduction in Tcell exhaustion markers (PD-1+Tim-3+) and shrinkage
CAR T 细胞长期暴露于肿瘤抗原可导致 CAR T 细胞耗竭和肿瘤扩张。为了扭转这种疲惫,我们开发了两种正交策略,专门针对用尽的 CAR T 细胞靶向有效的 TLR7 激动剂。我们在此证明,这两种策略都能使衰竭的 CAR T 细胞恢复活力,从而导致 T 细胞衰竭标志物 (PD-1 + Tim-3 + ) 的显着减少和 CAR T 细胞抗性肿瘤的缩小。

Pharmaceutical compositions comprising a poorly water soluble ionizable drug, a cationic species and a dispersion polymer are disclosed, together with a process for forming the compositions. The neutral form of the drug has (i) a solubility of less than 1 mg/ml, in aqueous solution at a pH between 6 and 7, (ii) a solubility of less than 20 mg/mL in a volatile organic solvent, and (iii) an acidic pKa value of greater than 5. At least 90 wt % of the drug in the solid dispersion being in a non-crystalline form. The drug, the cationic species, and the dispersion polymer constitute at least 80 wt % of the solid dispersion.

A general and catalytic α-arylation of cyclic 1,3-dicarbonyls have been developed, providing expedient access toward a wide range of high-value 2-aryl (hetero)cyclic 1,3-dicarbonyls. The key to success is through a cyclic iodonium ylide strategy. Our approach is base-free and exhibits broad substrate scope (>100 examples). Importantly, our approach allows late-stage modification and significantly simplifying
