N-Palmitoyl phenylalanine is an N-acylamide compound combining the long-chain saturated fatty acid palmitic acid with the essential amino acid L-phenylalanine through an amide bond. In nuclear extracts of HeLa cells, this compound inhibits pre-mRNA splicing activity (IC50 = ~150 µM); however, it does not exhibit splicing activity in whole HeLa cells.

在HeLa细胞核提取物中，本化合物可抑制pre-mRNA剪接活性（IC50 = ~150 µM），但在完整HeLa细胞中则未显示出此类活性。
