- Novel enmein-type diterpenoid hybrids coupled with nitrogen mustards: Synthesis of promising candidates for anticancer therapeutics
-
Natural derived enmein-type diterpenoids exert cytotoxicity against a wide range of human cancer cells. Yet their medicinal applications are hindered by insufficient potency for chemotherapy. Hence, a series of novel enmein-type diterpenoid hybrids coupled with nitrogen mustards were designed and synthesized to increase antitumor efficacy while reducing systemic toxicity. Most conjugates exhibited stronger antiproliferative activities than parent diterpenoids and nitrogen mustards, especially for multidrug-resistant tumor cell line Bel-7402/5-FU. Among them, compound E2 showed the most potent inhibitory activities in human leukemia HL-60 cells, human prostate cancer PC-3 cells, human liver cancer Bel-7402 cells and drug-resistant human liver cancer Bel-7402/5-FU cells with IC50 values of 7.83 μM, 3.97 μM, 0.77 μM and 2.07 μM, respectively. Additionally, high selectivity with selectivity index over 130 was also observed from cytotoxic evaluation between L-02 human normal liver cells and Bel-7402 malignant liver cells. Further studies on mechanism of action indicated that E2 induced both apoptosis and G1 phase cell cycle arrest in Bel-7402 hepatoma cells. Moreover, the dysfunction in mitochondrial pathway was also involved in E2 initiated apoptotic activation, which entailed the loss of mitochondrial membrane potential followed by upregulating the bax/bcl-2 ratio and increasing the expression of cytochrome c, p53, caspase-3 and -9. Overall, E2 has the potential to emerge as a promising drug candidate for cancer therapy.

- Improving the Potency of Cancer Immunotherapy by Dual Targeting of IDO1 and DNA
-
Herein we report the first exploration of a dual-targeting drug design strategy to improve the efficacy of small-molecule cancer immunotherapy. New hybrids of indoleamine 2,3-dioxygenase 1 (IDO1) inhibitors and DNA alkylating nitrogen mustards that respectively target IDO1 and DNA were rationally designed. As the first-in-class examples of such molecules, they were found to exhibit significantly enhanced anticancer activity in vitro and in vivo with low toxicity. This proof-of-concept study has established a critical step toward the development of a novel and effective immunotherapy for the treatment of cancers.

- Synthesis of scutellarein derivatives with antiproliferative activity and selectivity through the intrinsic pathway
-
To explore antitumor agents with potent efficacy and low toxicity, scutellarein derivatives with benzoic acid mustard (10a?c, 11a?c and 13a?c) were designed and synthesized. The antiproliferative activities of the target derivatives against A549, MCF-7 and Bel-7402 cancer cell lines were tested. Compound 10a showed the strongest potency with an IC50 value of 1.50 μM against MCF-7 cell line, and displayed low toxicity against human liver L-O2 normal cells (IC50 > 50 μM), showing specificity between normal and malignant cells. The mechanism studies revealed that 10a could induce apoptosis in MCF-7 cells, arrest MCF-7 cell cycle at the G1 phase and cause mitochondrial dysfunction in a concentration-dependant manner. Furthermore, the enhanced expression of the pro-apoptotic proteins caspase-9, caspase-3, Bax and cytochrome c, and the reduced expression of the anti-apoptotic protein Bcl-2 confirmed that 10a induced the intrinsic apoptosis pathway in MCF-7 cells. The potent antiproliferative activity and good selectivity guaranteed 10a a lead compound for the further development into anticancer therapeutics, especially for breast cancer.

- Synthesis of androstene oxime-nitrogen mustard bioconjugates as potent antineoplastic agents
-
In the present study, synthesis and antineoplastic activity of phenylacetic acid and benzoic acid nitrogen mustard conjugates of various steroidal oximes are reported for the first time. The conjugation was achieved through a more stable oxime-ester linkage and the resulting newly synthesized conjugates were evaluated in vitro on various human cancer cell lines for cytotoxicity. The extent of their alkylating activity was investigated by the in vitro colorimetric 4-(p-nitrobenzyl)pyridine (NBP) assay. The 17E-steroidal oxime-benzoic acid mustard ester 3β-acetoxy-17E-[p-(N,N-bis(2-chloroethyl)amino)]benzoyloxyimino-androst-5-ene (8) emerged as the most potent conjugate having significant cytotoxicity on most of the NCI 60-cell lines. Outstanding growth inhibition was observed on the IGROV1 ovarian cancer cell line with GI50?=?0.937?μM. In general, the D-ring derived androstene oxime-nitrogen mustard conjugates were found to possess better antineoplastic activity over a variety of cancer cells in comparison to those derived from other rings of the steroid skeleton.

- Design and synthesis of novel nitrogen mustard-evodiamine hybrids with selective antiproliferative activity
-
A series of novel nitrogen mustard-evodiamine hybrids were synthesized and evaluated for their antitproliferative properties. The antiproliferative activities of 10a–d, 11a–d, and 12a–d against four different kinds of human cancer cell lines (PC-3, HepG2, THP-1 and HL-60) and human normal peripheral blood mononuclear cells (PBMC) were determined. The results showed that all the target hybrid compounds exhibited antiproliferative activities against tested human tumor cell lines to some extent and no antiproliferative activities (>200 μM) against human normal PBMC cells. The antiproliferative selectivity between tumorous and normal cells was very useful for further antitumor drug development. Among the target compounds, 12c showed the strongest cytotoxicity against two tumor cell lines (THP-1 and HL-60) with IC50 values of 4.05 μM and 0.50 μM, respectively, and selected for further mechanism study in HL-60 cells. The results showed that 12c could induce HL-60 cells apoptosis and arrest at G2 phase at low sub-micromolar concentrations via mitochondria-related pathways.

- Design, synthesis and biological evaluation of novel sesquiterpene mustards as potential anticancer agents
-
Several novel series of sesquiterpene mustards (SMs) bearing nitrogen mustard and glutathione (GSH)-reactive α-methylene-γ-butyrolactone groups were successfully prepared for the first time and showed excellent antiproliferative activities in vitro. Among them, compounds 2e and 2g displayed the highest antiproliferative properties with IC50 values ranging from 2.5 to 8.7 μM. The selectivity of these two compounds was evaluated by SRB method against human cancer and normal hepatic cells (HepG2 and L02). The induction of apoptosis and effects on the cell cycle distribution with compounds 2e and 2g were investigated by Hoechst 33,258 staining and flow cytometry, which exhibited that they could induce selective cell apoptosis and cell cycle arrest in HepG2 and L02 cells. In addition, further investigation showed that compounds 2e and 2g could obviously inhibit the proliferation of HepG2 cells by inducing significant DNA cross-linking and depleting GSH in cell media. The good cytotoxicity and selectivity of compounds 2e and 2g pointed them as promising leads for anticancer drug design.

- Novel hybrids of natural oridonin-bearing nitrogen mustards as potential anticancer drug candidates
-
A series of novel hybrids from natural product oridonin and nitrogen mustards were designed and synthesized to obtain more efficacious and less toxic antitumor agents. The antiproliferative evaluation showed that most conjugates were more potent than their parent compounds oridonin and clinically used nitrogen mustards against four human cancer cell lines (K562, MCF-7, Bel-7402, and MGC-803). Furthermore, the representative compounds 16a-c exhibited antiproliferative activities against the multidrug resistant cell lines (SW620/AD300 and NCI-H460/MX20). It was shown that the most effective compound 16b possesses a strong inhibitory activity with an IC50 value 21-fold lower than that of oridonin in MCF-7 cells and also exhibits selective cytotoxicity toward the cancer cells. Intriguingly, compound 16b has been demonstrated to significantly induce apoptosis and affect cell cycle progression in human hepatoma Bel-7402 cells.

- Synthesis, biological evaluation and molecular docking studies of amide-coupled benzoic nitrogen mustard derivatives as potential antitumor agents
-
A series of amide-coupled benzoic nitrogen mustard derivatives as potential EGFR and HER-2 kinase inhibitors were synthesized and reported for the first time. Some of them exhibited significant EGFR and HER-2 inhibitory activity. Of all the studied compounds, compounds 5b and 5t exhibited the most potent inhibitory activity, which was comparable to the positive control erlotinib. Docking simulation was performed to position compounds 5b and 5t into the EGFR active site to determine the probable binding model. Antiproliferative assay results indicated that some of the benzoic nitrogen mustard derivatives possessed high antiproliferative activity against MCF-7. In particular, compounds 5b and 5t with potent inhibitory activity in tumor growth inhibition may function as potential antitumor agents.
