The psychosocial burden akin to cutaneous conditions such as cancer and hyperpigmentation disorders, make their management very sensitive. Current therapeutic interventions, are associated with side-effects, cost, invasiveness bioavailability issues. Herein, 26 new pyrazole pyrazolone compounds were synthesized via microwave-assisted reactions pharmacokinetic parameters ADMET predicted by in-si...

Subjects Methods: traditional Soxhlet apparatus was used to prepare crude plant using organic solvents. agar well diffusion method explore anti-candida, MTT assay assess activity. Results: With IC50 values 250 g/ml more than 1000 g/m...

In recent years, immunotherapy for advanced melanoma has been gaining increased attention. The efficacy of anti-cytotoxic T-lymphocyte antigen 4 antibodies, anti-programmed cell death 1 antibodies, and the BRAF(V600E) kinase inhibitor has been proven in metastatic melanoma. At the same time, adoptive cell transfer has significant effects against metastatic melanoma; however, it is difficult to ...

Recent studies have indicated that therapeutic antibodies targeting PD-L1 show remarkable efficacy in clinical trials in multiple tumors and that a melanoma cell-intrinsic PD-1: PD-L1 axis promotes tumor growth. However, few studies have shown tumor-intrinsic PD-L1 effects in malignant melanoma initiating cells (MMICs). Here, we aim to determine the possible regulatory effects of PD-L1 on MMICs...

Reduction in the expression of the anti-survival BH3-only proteins PUMA and Bim is associated with the pathogenesis of melanoma. However, we have found that the expression of the other BH3-only protein Noxa is commonly upregulated in melanoma cells, and that this is driven by oncogenic activation of MEK/ERK. Immunohistochemistry studies showed that Noxa was expressed at higher levels in melanom...

Melanoma is the most aggressive and deadly type of skin cancer. Surgical resection with or without lymph node sampling is the standard of care for primary cutaneous melanoma. Adjuvant therapy decisions may be informed by careful consideration of prognostic factors. High-dose adjuvant interferon alpha-2b increases disease-free survival and may modestly improve overall survival. Less toxic altern...

The efficacy of nivolumab is greater than that of other anti-melanoma drugs, so nivolumab-based combined therapies that enhance anti-tumor immune responses in patients with metastatic melanoma are of great interest to dermato-oncologists. As we have previously reported, IFN-β enhances the anti-tumor immune response of anti-PD-1 antibodies against B16F10 melanoma in vivo. To explore the potentia...

BACKGROUND Melanoma therapy is challenging, especially in advanced cases, due to multiple developed tumor defense mechanisms. Photodynamic therapy (PDT) might represent an adjuvant treatment, because of its bimodal action: tumor destruction and immune system awakening. In this study, a combination of PDT mediated by a metal substituted phthalocyanine-Gallium phthalocyanine chloride (GaPc) and M...

Proteases are crucial for the spread of cancer cells from a primary tumor to the site of secondary growth. This study examined the ability of IFNÁ and TNF· to stimulate a better invasiveness in B16 murine melanoma cells, and investigated whether this enhanced ability was related to a higher expression of protease activities, such as urokinase plasminogen activator (uPA) and its receptor (uPAR),...

Blockade of immune checkpoint proteins (e.g., CTLA-4, PD-1) improves overall survival in advanced melanoma; however, therapeutic benefit is limited to only a subset of patients. Because checkpoint blockade acts by "removing the brakes" on effector T cells, the efficacy of checkpoint blockade may be constrained by the limited pool of melanoma-reactive T cells in the periphery. In the thymus, aut...
