(2S)-2-Amino-4-(butylsulfonimidoyl)butanoic acid (BD136012) is a building block containing a sulfoximine group. Several CDK and ATR inhibitors have exemplified the utilization of the NH sulfoximine group as abioisostere for a sulfonamide group to overcome the main project hurdles of aqueous solubility, sulfonamide-mediated off-target activity and IP. Moreover, its NH group could be expediently further functionalized through Buchwald-Hartwig coupling reaction and multifarious nucleophilic reactions.. Recommended Products is: 4381-25-3 and 1621962-30-8.
With the continuous development of cancer nanotechnol., an important trend in the research is to combine the broad application prospects of functional nanomaterials with recent biol. discoveries and technol. advances. Herein, a cancer cell membrane-camouflaged gold nanocage loading doxorubicin (DOX) and L-buthionine sulfoximine (BSO) (denoted as m@Au-D/B NCs) was constructed as an innovative nanoplatform to confer promising cancer combination therapy by evoking effective ferroptosis and immune responses. Briefly, the loading of BSO and DOX could induce ferroptosis through simultaneous effective glutathione (GSH) consumption and reactive oxygen species (ROS) accumulation. Gold nanocages (AuNCs) with distinct anti-tumor application performance was utilized as ideal nanocarrier for drug loading, evoking photothermal effects and photochem. catalysis to generate more ROS under near-IR (NIR) irradiation Moreover, m@Au-D/B NCs-mediated photothermal therapy (PTT) combined with ROS production could repolarize the tumor-associated macrophages (TAMs) from pro-tumor (M2) phenotype to anti-tumor (M1) phenotype, thus improving tumor-suppressive immune environment and then promoting the activation of effector cells and release of pro-inflammatory cytokines, in which the antitumor responses were evoked robustly in a methodical approach. The anti-tumor effects in vivo implied that m@Au-D/B NCs could significantly inhibit tumor growth without severe toxicity. Hence, this homotypic targeting nanosystem could offer an auspicious anticancer access by triggering combination cancer therapy via ferroptosis and tumor-associated macrophage repolarization mechanism.
