Nomilin

Cancer: Melanoma, breast cancer

Action: Anti-angiogenic

Nomilin is a triterpenoid present in common edible citrus fruits (Citrus grandis [(L.) Osb.], Citrus unshiu [(Swingle) Marcow.] and Citrus reticulata (Blanco)) with putative anti-cancer properties.

Melanoma

Nomilin possess anti-metastatic action, inducing metastasis in C57BL/6 mice through the lateral tail vein using highly metastatic B16F-10 melanoma cells. Administration of nomilin inhibited tumor nodule formation in the lungs (68%) and markedly increased the survival rate of the metastatic tumor–bearing animals. Nomilin showed an inhibition of tumor cell invasion and activation of matrix metalloproteinases. Treatment with nomilin induced apoptotic response.

Nomilin treatment also exhibited a down-regulated Bcl-2 and cyclin-D1 expression and up-regulated p53, Bax, caspase-9, caspase-3, p21, and p27 gene expression in B16F-10 cells. Pro-inflammatory cytokine production and gene expression were found to be down-regulated in nomilin-treated cells. The study also reveals that nomilin could inhibit the activation and nuclear translocation of anti-apoptotic transcription factors such as nuclear factor (NF)-κB, CREB, and ATF-2 in B16F-10 cells (Pratheeshkumar et al., 2011).

Breast Cancer; ER+

A panel of 9 purified limonoids, including limonin, nomilin, obacunone, limonexic acid (LNA), isolimonexic acid (ILNA), nomilinic acid glucoside (NAG), deacetyl nomilinic acid glucoside (DNAG), limonin glucoside (LG) and obacunone glucoside (OG) as well as 4 modified compounds such as limonin methoxime (LM), limonin oxime (LO), defuran limonin (DL), and defuran nomilin (DN), were screened for their cytotoxicity on estrogen receptor (ER)-positive (MCF-7) or ER-negative (MDA-MB-231) human breast cancer cells. Findings indicated that the citrus limonoids may have potential for the prevention of estrogen-responsive breast cancer (MCF-7) via caspase-7 dependent pathways (Lin et al., 2013).

Blocks Angoigenesis

Nomilin significantly inhibited tumor-directed capillary formation. Serum pro-inflammatory cytokines such as IL-1β, IL-6, TNF-α and GM-CSF and also serum NO levels were significantly reduced by the treatment of nomilin. Administration of nomilin significantly reduced the serum level of VEGF, a pro-angiogenic factor and increased the anti-angiogenic factors IL-2 and TIMP-1. Nomilin significantly retarded endothelial cell proliferation, migration, invasion and tube formation. These data clearly demonstrate the anti-angiogenic potential of nomilin by down-regulating the activation of MMPs, production of VEGF, NO and pro-inflammatory cytokines as well as up-regulating IL-2 and TIMP (Pratheeshkumar et al., 2011).

Astragalus (huang qi)

Cancer: Non-small-cell lung cancer, breast, colon, stomach

NSCLC; Chemotherapy

Guo et al. (2012) reported that treatment with Astragalus polysaccharide (APS) injections integrated with vinorelbine and cisplatin significantly improved quality of life in patients with advanced non-small-cell lung cancer over vinorelbine and cisplatin alone.

NSCLC

Astragalus injection (AI) combined with chemotherapy can significantly improve the QOF in NSCLC patients of advanced stage. The effective rate in the treated group was 40.0% and in the control group was 36.7%, the mean remission rate in the treated and control group was 5.4 months and 3.3 months, the median survival period 11 months and 7 months, and the 1-year survival rate 46.75% and 30.0%, respectively; the differences of these indexes between the two groups were all significant (P < 0.05). Moreover, the clinical improving rate and QOF elevation rate in the treated group was 80.4% and 43.3%, as compared with those in the control group (50.0% and 23.3% respectively); the difference was also significant (P < 0.01) (Zou & Liu, 2003).

Breast Cancer

In physiological dose E2, Astragalus mongholicus injection inhibited MCF-7 breast cancer cells proliferation at all concentration groups. As time lasting, Astragalus mongholicus injection showed better inhibitory effect than TAM (P<0.05). Among 2 x 10(-1) g/mL-2 x 10(-4) g/mL concentration, Astragalus mongholicus injection significantly increased the proliferative percent of G0/G1 and S-phase cell, decreased percent of G2-M phase cell (P<0.05) at 24 hours. After cocultured 72 hours, Astragalus mongholicus injection increased the rate of apoptosis to 16.7% at 2 x 10(-1) g/mL concentration (Zhou, Liu, & Tan, 2009).

Acute Exacerbations, Respiratory Failure in Chronic Obstructive Pulmonary Disease

A total of 112 patients with acute chronic obstructive pulmonary disease (AECOPD)were randomly divided into the treatment group (56 cases) and control group (56 cases). The treatment group received a 40 mL astragalus injection, with 5% glucose, 250 mL intravenous drip once a day at the start of conventional therapy. The control group received conventional therapy only. The therapeutic course of both groups was 14 days, and clinical therapeutic effects were observed. Serum levels of TNF-α>, IL-8, IL-2, lung function and blood gas analysis index of both groups were measured before and after treatment. The treatment group”s effectiveness rate was 94.64%, compared to the control group”s 67.86%, which was statistically significant (P<0.05).

Astragalus injection may significantly decrease the serum levels of TNF-α and IL-8, and increase the level of IL-2. It may improve the lung function and the curative effect in the patients with AECOPD (Xiong, Guo, & Xiong, 2013).

Residual Renal Function

The effect of astragalus injection on hemodialysis patient”s RRF (residual renal function, RRF) was observed.

Sixty hemodialysis patients with a RRF of more than 2ml/min were randomly divided into either an astragalus injection treatment group or a control group treated with normal saline. One hour prior to hemodialysis completion, the treatment group was administered an astragalus injection of 30ml, while the control group was given 30 ml of normal saline. Follow up after 6 months compared data of daily urine output and RRF.

Astragalus injection can potentially delay the rate of daily urine output reduction and protect RRF to some extent (Qi et al., 2013).

Stomach Cancer, Colon Cancer; Oxaliplatin-induced Neurotoxicity

40 patients with stomach or colon cancer were enrolled in the study. Patients comprised of 23 men and 17 women, from the ages of 32-75 years (mean age 60 years), and were randomly divided into two groups: the test group and the control group (20 cases in each group). All patients were treated with one cycle of an Oxaliplatin-containing chemotherapy regimen, entailing: oxaliplatin 130 mg/m2 on day 1, fluorouracil 0.5 g on days 1-5, and calcium foliate 0.2 g on days 1-5. In the test group 30 ml of Huangqi injection was added to the regimen on days 1-7. The manifestation of peripheral neurotoxic reactions were observed and nerve growth factor levels were measured.

In the control group, 2 patients had grade 0 toxicity, 10 had grade 1 toxicity, 6 had grade 2 toxicity, and 2 had grade 3 toxicity. In the test group, 14 patients had grade 0 toxicity and 6 had grade 1 toxicity. The incidence rate of neurotoxicity in the test and control groups was 30% and 90%, respectively. In the test and control groups, the nerve growth factor levels were (167 ± 10) ng/ml and (204 ± 19) ng/ml before chemotherapy, as well as (152 ± 8) ng/ml and (133 ± 12) ng/ml 2 days after chemotherapy, respectively. In the control group, the nerve growth factor levels were markedly decreased 2 days after chemotherapy compared to before chemotherapy. The difference between the two groups was statistically significant (P < 0.01).

Huangqi injection has some degree of efficacy in the prevention and treatment of Oxaliplatin-induced neurotoxicity (Cui, Li, Tan, & Li, 2009).

Myelosuppression

Astragalus membranaceus injection (AMI), administered at (500 mg/kg) improved the hematopoietic microenvironment by enhancing the BMSC survival and proliferation of colony-forming unit-fibroblast (CFU-F) formation, production of IL-6 as well as Granulocyte-macrophage colony-stimulating factor (GM-CSF) by BMSC and bcl-2 protein and mRNA expression in BMSC, which promoted myelopoiesis. The data may provide a mechanistic basis for applying this ancient Chinese herb to promote hematopoiesis as an efficacious adjuvant therapy against myelosuppression induced by anti-cancer therapy (Zhu & Zhu, 2007).
