ppc-1

Ppc-1 is a chemical compound known for its inhibitory effects on the Gram-negative periodontopathogen Porphyromonas gingivalis. It acts as a mitochondrial uncoupler, enhancing mitochondrial oxygen consumption without affecting ATP production. Additionally, Ppc-1 serves as a cell-permeate inhibitor of interleukin-2 (IL-2). This compound exhibits various beneficial activities, including anti-obesity, antibacterial, and anti-inflammatory properties.

PPC-NHS ester is a cleavable linker vital in ADC synthesis. PPC-NHS ester joins cytotoxic drugs to antibodies, enabling precise delivery to cells or proteins. The cleavable nature ensures controlled drug release, optimizing ADC effectiveness.

PQA-18 是p21激活激酶2（PAK2；IC50 = 10 nM）的有效抑制剂，并作为Ppc-1（产品编号42352）衍生物展现出免疫抑制特性。该化合物能够降低由刀豆A（产品编号14951）刺激的Jurkat T细胞中IL-2的生成（IC50 = 400 nM）。在应用0.1% PQA-18的情况下，NC Nga小鼠模型显示异位性皮炎的严重程度、血清IgE水平及皮肤厚度有所减轻。此外，0.05%的剂量可有效减少该小鼠模型中皮肤神经纤维的密度。PQA-18（4 mg kg）还在大鼠小肠移植模型中显著提高了移植物的存活率。

PPC-NB is a glutathione-cleavable linker used in antibody-drug conjugates (ADC) [1].
