N1-(Arylalkyl)homospermidines (1c-1f) and terminally piperazine-substituted homospermidine conjugates (2a-2e) were synthesized and evaluated for cytotoxicity in mouse leukemia L1210, alpha-difluoromethylornithine (DFMO)-treated L1210, melanoma B16, spermidine (SPD)-treated B16, and HeLa cell lines.
This study was conducted to examine the polyamine transporter (PAT) recognization and antitumor effects of anthracenymethyl homospermidine (ANTMHspd) and its apoptotic mechanism in B16 melanoma cells. ANTMHspd promoted a dose-dependent apoptosis in B16 melanoma cells and the apoptosis was associated
An efficient modular synthesis of N(1)-substituted triamines containing different tether lengths between nitrogen centers was developed. A series of N(1)-(9-anthracenylmethyl)triamines were evaluated for biological activity in L1210 (murine leukemia), alpha-difluoromethylornithine (DFMO)-treated
A series of polyamine conjugates were synthesized and evaluated for their ability to target the polyamine transporter (PAT) in two Chinese hamster ovary (CHO) cell lines (PAT-active CHO and PAT-inactive CHOMG). This systematic study identified salient features of the polyamine architecture required
A series of unsymmetrically substituted polyamine derivatives were prepared and their cytotoxicities in mouse leukemia L1210, melanoma B16, and HeLa cells were investigated. The in vitro cytotoxicity revealed that these conjugates could recognize the polyamine transporter, and the N-ethyl modified
