CAL-101 (Idelalisib; GS-1101) is a highly selective and potent p110δ small molecule inhibitor (half-maximal effective concentration [EC(50)] = 8nM). CAL-101 inhibits CLL cell chemotaxis toward CXCL12 and CXCL13 and migration beneath stromal cells (pseudoemperipolesis). CAL-101 (GS-1101) also down-regulates secretion of chemokines in stromal cocultures and after BCR triggering. CAL-101 reduces survival signals derived from the BCR or from nurse-like cells, and inhibits BCR- and chemokine-receptor-induced AKT and MAP kinase (ERK) activation. In stromal cocultures, CAL-101 sensitizes CLL cells toward bendamustine, fludarabine, and dexamethasone. CAL-101 (GS-1101) blocked constitutive phosphatidylinositol-3-kinase signaling, resulting in decreased phosphorylation of Akt and other downstream effectors, an increase in poly(ADP-ribose) polymerase and caspase cleavage and an induction of apoptosis. CAL-101 displays a dual mechanism of action, directly decreasing cell survival while reducing interactions that retain CLL cells in protective tissue microenvironments.

| Cell Experiment | |
|---|---|
| Cell lines | Primary cortical neurons, astrocytes or microglia |
| Preparation method | Assaying TNF secretion For drug treatments, cells were incubated with IC87114, CAL-101 (AbMole, M1945) and LPS, glucose-free Locke’s buffer, or a combination thereof. For TNF surface delivery assay18, 32, TNF-converting enzyme inhibitor was added at the same time as LPS or included in the glucose-free Locke’s buffer. All inhibitors were reconstituted in Dimethyl sulfoxide (AbMole) with final concentrations <0.1% in assays. To determine the levels of secreted TNF, a commercial BD OptEIA TNF Elisa Set II kit was used to quantify cytokine concentration in samples according to the manufacturer’s instructions. |
