aforementioned compound classes. Enantioresolution was achieved by simply adding native β‐cyclodextrin, acetyl‐β‐cyclodextrin, 2‐hydroxypropyl‐β‐cyclodextrin, or carboxymethyl‐β‐cyclodextrin as chiral selector additives to the background electrolyte. Fifty‐one chiral NPS served as analytes mainly purchased from online vendors via the Internet. Using 10 mM of the aforementioned β‐cyclodextrins in a 10 mM

Therapeutic combinations of a CD 19 inhibitor and a Bruton's tyrosine kinase (BTK) inhibitor are described. In some embodiments, the invention provides pharmaceutical compositions comprising combinations of a CD 19 inhibitor and a BTK inhibitor and methods of using the pharmaceutical compositions for treating a disease, in particular a cancer, such as a hematological malignancy. A combination of a BTK inhibitor and a CD 19 inhibitor, such as a CD19-targeted antibody or a CD19-targeted chimeric antigen receptor expressing T cell or NK cell, and compositions and uses thereof are disclosed. Combinations of a BTK inhibitor and a CD 19 inhibitor with a programmed death- 1 (PD-1) or PD-1 ligand (PD-L1) inhibitor and compositions and uses thereof are also disclosed.

efficient route for methylation and acetylation of aza-heteroarenes using PEG-400 under O2 and TsOH·H2O for the first time by tuning the reaction conditions using a different set of starting materials. The key features of the current protocol are oxidative C–O and C–C bond scission under metal-free conditions with good functional group tolerance, and a broad substrate scope. The potential applicability
Microspheres are produced by contacting a solution of a macromolecule or small molecule in a solvent with an antisolvent and a counterion, and chilling the solution. The microspheres are useful for preparing pharmaceuticals, nutraceuticals, cosmetic products and the like of defined dimensions.

4(3H)-Quinazolinones are well known as antihypertensive, antidiabetic, antiinflammatory, anticonvulsant, and antibacterial agents.' Some of the compounds are natural products? Thus, many synthetic methods have been reported. The simplest and most straightforward procedure was developed by Niementowski in 1899 and improved by Grimmel et al. in 1 9464 who reported that 4(3H)-quinazolinones could be synthesized
