Anticancer agent 296

Anticancer agent 296 is a potent anticancer agent that activates the PERK-eIF2α-CHOP signaling pathway to induce endoplasmic reticulum stress, thereby regulating caspase and Bcl-2 family proteins, ultimately leading to apoptosis. Anticancer agent 296 increases intracellular levels of reactive oxygen species (ROS), reduces mitochondrial membrane potential, and promotes Ca²⁺ release. Anticancer agent 296 suppresses cell colony formation and S-phase cell proliferation, and induces autophagy. Anticancer agent 296 is applicable for research on non-small cell lung cancer (NSCLC).

Anticancer agent 296 (Compound 5b) (1.25-10 μM; 48 h) potently inhibits proliferation of A549 and HeLa cancer cells with IC₅₀ values of 3.88 μM and 3.89 μM, respectively, and has a favorable safety margin against normal cells^[1].
Anticancer agent 296 (1.94-3.88 μM; 48 h; 24 h with Mitomycin C (HY-13316) pre-treatment) effectively inhibits migration of A549 cells in a concentration-dependent manner, with 3.88 μM reducing wound healing to 8.19%^[1].
Anticancer agent 296 (1.94-7.76 μM; 24 h) downregulates FAK protein expression in A549 cells, contributing to inhibited migration, and also activates the PERK-eIF2α-CHOP ER stress pathway and the endogenous apoptotic pathway in A549 cells by regulating key proteins^[1].
Anticancer agent 296 (1.94-7.76 μM; 7 days) effectively inhibits colony formation of A549 cells at concentrations ≥3.88 μM^[1].

Anticancer agent 296 (1.94-7.76 μM; 24 h) induces S phase arrest in A549 cells in a dose-dependent manner, with 7.76 μM increasing S phase to 31.33% by downregulating cell cycle-related proteins^[1].
Anticancer agent 296 (1.94-7.76 μM; 24 h) decreases mitochondrial membrane potential in A549 cells in a concentration-dependent manner^[1].
Anticancer agent 296 (1.94-7.76 μM; 24 h) increases ROS levels in A549 cells^[1].
Anticancer agent 296 (3.88-7.76 μM; 24 h) induces oxidative stress in A549 cells by reducing GSH and increasing MDA levels^[1].
Anticancer agent 296 (1.94-7.76 μM; 24 h) increases intracellular calcium concentration in A549 cells, with 7.76 μM inducing a 1.68-fold increase^[1].
Anticancer agent 296 (3.88 μM; 24 h) induces endoplasmic reticulum stress in A549 cells via the PERK pathway, as evidenced by ER vacuolization^[1].
Anticancer agent 296 (1.94-7.76 μM; 24 h) induces early apoptosis in A549 cells, with 7.76 μM increasing early apoptosis to 11.14%^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
