A series of 18 new imidazo[2,1-b]thiazole derivatives was synthesized. Their in vitro antiproliferative activities against A375P human melanoma cell line and NCI-60 cell line panel were tested. Compounds 15, 16, 18, 22, 26-28, and 31 showed superior potency against A375P to sorafenib. In addition, compounds 26 and 27 showed selectivity toward melanoma cell lines than for other cancer types. Both compounds exerted sub-micromolar IC(50) values over 7 (including A375P) and 6 melanoma cell lines, respectively. In silico studies are also reported. ADME profiling, in silico toxicity, drug-likeness, and drug-score data of compounds 26 and 27 are promising.

Melanoma is a devastating form of skin cancer characterized by a high mutational burden, limited treatment success, and dismal prognosis. Although immunotherapy and targeted therapies have significantly revolutionized melanoma treatment, the majority of patients fail to achieve durable responses, highlighting the urgent need for novel therapeutic strategies. Ferroptosis, an iron-dependent form of regulated cell death driven by the overwhelming accumulation of lipid peroxides, has emerged as a promising therapeutic approach in preclinical melanoma models.

Inhibitors of the PD-1/PD-L1 immune checkpoint have revolutionized cancer treatment. However, the clinical response remains limited, with only 20% of patients benefiting from treatment and approximately 60% of PD-L1-positive patients exhibiting resistance. One key factor contributing to resistance is the externalization of phosphatidylserine (PS) on the surface of cancer cells, which suppresses immune responses and promotes PD-L1 expression, further hindering the efficacy of PD-L1 blockade therapies.

Patients diagnosed with metastatic basal cell carcinoma (BCC) have a poor prognosis. The current standard of care for adults with locally advanced or metastatic BCC who are not candidates for surgery or radiation therapy is treatment with hedgehog pathway inhibitors (HHIs). For patients who progress while on this therapy, further treatment options are limited.

Despite significant strides in anti-melanoma therapies, resistance and recurrence remain major challenges. A deeper understanding of the underlying biology of these challenges is necessary for developing more effective treatment paradigms. Melanoma single-cell data were retrieved from the Broad Single Cell Portal (SCP11).
