New derivatives of phaeosphaeride A (PPA) were synthesized and characterized. Anti-tumor activity studies were carried out on the HCT-116, PC3, MCF-7, A549, К562, NCI-Н929, Jurkat, THP-1, RPMI8228 tumor cell lines, and on the HEF cell line. All of the compounds synthesized were found to have better efficacy than PPA towards the tumor cell lines mentioned. Compound 6 was potent against six cancer cell lines, HCT-116, PC-3, K562, NCI-H929, Jurkat, and RPMI8226, showing a 47, 13.5, 16, 4, 1.5, and 7-fold increase in anticancer activity comparative to those of etoposide, respectively. Compound 1 possessed selectivity toward the NCI-H929 cell line (IC …

Neoplastic growths represent a unique challenge for the host immune system. As they are indeed derived from self, many of the same mechanisms operating to prevent autoimmunity also provide an umbrella beneath which malignant cells are free to proliferate.1 Central among these immune regulatory boundaries are an influential subset of lymphocytes known as T regs. Hypothesized to exist decades ago, yet eluding definitive characterization until relatively recently, T regs have been demonstrated to play a crucial role in the proper functioning of the immune system as a whole. They may also, however, represent one of the primary obstacles to successful …
