Herein, the synthesis of novel hydrophobic and hydrophilic cobinamides via aminolysis of vitamin B12 derivatives that activate soluble guanyl cyclase (sGC) is presented. Unlike other sGC regulators, they target the catalytic domain of sGC and show higher activity than (CN)2Cbi.

Chemotherapy is still one of the major approaches in triple-negative breast cancer (TNBC) treatment. The development of new formulations for classic chemotherapeutic drugs remains interests in studies. Camptothecin (CPT) is powerful antitumor agents in TNBC treatment though its clinic applications are limited by its low water solubility and systemic toxicity.

Herein, a kind of N-doped fluorescent carbon dots (N-CDs) were prepared by using melamine and carboxymethyl cellulose (CMC) as precursors through a straightforward hydrothermal method. The designed sensor displayed a uniform nanoscale distribution, excellent hydrophilicity, and strong fluorescence emission with a fluorescence quantum yield of 37.98%.

Mertansine (DM1), a potent tumor-killing maytansinoid, requires conjugation to antibodies or incorporation into nanocarriers due to its high toxicity. However, these carriers often result in undesirable biodistribution, leading to rapid and long-term accumulation in the kidneys or liver and potentially increased toxicity. To overcome this limitation, we used the hydrophilic, biocompatible, and stealth properties of polyacrylamide (PAAm) as a scaffold to develop water-soluble PAAm-DM1 polymer prodrugs, leveraging PAAm's previous success in delivering paclitaxel via subcutaneous administration.
