rhinacanthus nasutus/neoplasms

Three naphthoquinone derivatives, rhinacanthin-C (1), -D (2) and -N (3) were isolated from the leaves of Rhinacanthus nasutus extract and were tested for anti-inflammatory activity. The result indicated that all three compounds possessed very potent anti-inflammatory activity against

Centella asiatica (CA) and Rhinacanthus nasutus (RN) are Thai medicinal plants traditionally used to treat a variety of disorders including inflammatory conditions and infections. Nitric oxide (NO) produced from activated macrophages plays a role in both inflammatory and anti-inflammatory processes.

Rhinacanthus nasutus KURZ. (Acanthaceae) has been used as Thai traditional medicine for the treatment of various cancers. Recently, we reported that rhinacanthins, active components of the plant, had antiproliferative activity against human cancer line cells. In the present study, we investigated

BACKGROUND Thai medicinal preparation of Khampramong Temple has been used for cancer treatment more than ten years ago. It is composed of eleven herbs. Many anticancer drugs exhibited antimicrobial activity as antitumor antibiotics such as the anthracycline group [daunorubicin] and quinone group

Rhinacanthin-C is a major bioactive naphthoquinone ester found in Rhinacanthus nasutus Kurz (Acanthaceae). This compound has potential therapeutic value as an anticancer and antiviral agent. In this study, we investigated an enhancement effect of rhinacanthin-C on doxorubicin cytotoxicity in human

Rhinacanthus nasutus (L.) Kurz (Acanthaceae) is known as traditional medicine for the treatment of various diseases, such as cancer, fungal infections, herpes virus infections and several types of skin diseases in South-East Asian countries. In this study, eight compounds 1-8 were isolated from the

Rhinacanthus nasutus Kurz, a Thai medicinal plant which possess antiproliferative and pro-apoptotic effects on human cancer cells, was examined for chemopreventive potential against colonic neoplasms induced by azoxymethane (AOM) combined with dextran sodium sulfate (DSS) in mice. Male ICR mice were

BACKGROUND We recently reported that the MeOH extract of aerial parts and root of Rhinacanthus nasutus showed diverse biological activity, with most activity being concentrated into the EtOAc layer separated by sequential organic solvent extractions. In the present study, the EtOAc extracts were

BACKGROUND The MeOH extracts from aerial part and roots of Rhinacanthus nasutus were investigated for new biological activities. METHODS The MeOH extract of the root was stepwise separated by organic solvents into n-hexane, EtOAc, n-BuOH and H(2)O layer fractions. Cytotoxic activity against human

We previously observed that rhinacanthins-C, -N and -Q, three main naphthoquinone esters isolated from the roots of Thai medicinal plant; Rhinacanthus nasutus KURZ. (Acanthaceae) induced apoptosis of human cervical carcinoma HeLaS3 cells. Since these rhinacanthins showed limited solubility in

We previously observed that rhinacanthins, which are the main naphthoquinone esters isolated from the roots of a Thai medicinal plant, Rhinacanthus nasutus KURZ. (family Acanthaceae), suppress the growth of Meth-A sarcoma in the tumor-bearing mice and that rhinacanthin-N has the strongest antitumor

Rhinacanthone, a main bioactive naphthoquinone, isolated from roots of Rhinacanthus nasutus KURZ, (family Acanthaceae), a Thai traditional medicine, has been reported to possess anticancer effects, although the anticancer mechanism is still unclear. Therefore, we investigated the effects of

Rhinacanthus nasutus (L.) Kurz, a traditional Chinese herb possessing antioxidant and anti-cancer activities, has been reported to contain functional components like carotenoids and chlorophylls. However, the variety and amount of chlorophylls remain uncertain. The objectives of this study were to

Rhinacanthin-M, -N and -Q, natural products isolated from the medicinal plant Rhinacanthus nasutus, and 39 novel naphthoquinone esters have been synthesized in excellent yield by esterification of naphthoquinone-3-(propan-3'-ols) with benzoic or naphthoic acids. Almost all the naphthoquinone esters

BACKGROUND We recently reported that the ethyl acetate (EtOAc)-soluble fraction of the methanol extract of the root of Rhinacanthus nasutus showed tumor-specific non-apoptotic cytotoxicity and antiosteoclastogenic activity. In the present study, we investigated whether five rhinacanthins, mostly
