  • Melissa parviflora Benth. is an aromatic perennial herb of Lamiaceae family. It is one of the most influencial plant and used from centuries in Unani system of medicine for the treatment of various malady such as Epilepsy (mirgi), hemiplegia (falij), migraine (shaqeeqa), insomnia (sehar), indigestion (sue hazm) and palpitation (khafqaan) etc. The Persian physician Avicenna endorsed it for heart problems. It has antitubercular, antipyretic, analgesic and stomachic properties, also used to remove bad breath from mouth, strengthen the gums but its main action is as a tranquillizer and nervine relaxant, it is greatly esteemed for its calming properties. Preliminary performed phytochemical analysis revealed that tannin, flavonoid and saponins are the major components of the plant extract. The plants containing saponins or flavonoids exhibit anticonvulsant activity whereas the flavonoids show various biological activities including antioxidant, anti-inflammatory and cytotoxic-antitumor etc. Keeping in view the tremendous medicinal importance of the plant Badranjboya in Unani Medicine, this review provides updated information on its phytochemistry, therapeutic uses and pharmacological properties.

  • Abnormal changes in skin color induce significant cosmetic problems and affect quality of life. There are two groups of abnormal change in skin color; hyperpigmentation and hypopigmentation. Hyperpigmentation, darkening skin color by excessive pigmentation, is a major concern for Asian people with yellowe-brown skin. A variety of hypopigmenting agents have been used, but treating the hyperpigmented condition is still challenging and the results are often discouraging. Panax ginseng has been used traditionally in eastern Asia to treat various diseases, due to its immunomodulatory, neuroprotective, antioxidative, and antitumor activities. Recently, several reports have shown that extract, powder, or some constituents of ginseng could inhibit melanogenesis in vivo or in vitro. The underlying mechanisms of antimelanogenic properties in ginseng or its components include the direct inhibition of key enzymes of melanogenesis, inhibition of transcription factors or signaling pathways involved in melanogenesis, decreasing production of inducers of melanogenesis, and enhancing production of antimelanogenic factor. Although there still remain some controversial issues surrounding the antimelanogenic activity of ginseng, especially in its effect on production of proinflammatory cytokines and nitric oxide, these recent findings suggest that ginseng and its constituents might be potential candidates for novel skin whitening agents.

  • In order to improve cultivation technuque of C. lanceolata, natural ABA was treated with foliar application periodically during differenctitation of node. The higher is concentration and the earier its foliar application was, the shoter plant height was. Especially, when $10mg;.L{-1}$ of ABA was treated at differentiated stage of 3rd node, plant height was inhibited to 60% of control. But leaf length, leaf width, and number of branches have no significant differnence in comparison wiht control. The fresh weight of subterranean part was similar to control independent of treat-time in the case of $10mg;.L{-1}$. When 1,5 and $10mg;.L{-1}$ of ABA were treated at initial differentiated node stage, plant height inhibited to 20~30% of control, but subterranean part was similar to control. All treatement showed slight antitumor activity by the P388 cytotoxic screening test.

  • The 3-weekly regimen of carboplatin and paclitaxel is the backbone of first line adjuvant chemotherapy for advanced ovarian cancer. The landmark Japanese Gynaecologic Oncology Group (JGOG) 3016 study demonstrated significant improvements in progression-free survival and overall survival with dose dense weekly administration of paclitaxel in combination with 3-weekly carboplatin. However, efforts to replicate these benefits have failed in subsequent phase III trials. Weekly paclitaxel is purported to have enhanced antitumor activity, with stronger anti-angiogenic effects, and yet is better tolerated. In this review, we explore the rationale for dose dense weekly paclitaxel, and compare the relevant trials as well as quality of life considerations. Possible reasons for the difference in outcomes between the JGOG 3016 and other studies are reviewed, with a focus on how the addition of bevacizumab, the variations between histological and molecular subtypes of epithelial ovarian cancers, and ethnic pharmacogenetic differences may potentially affect the efficacy of dose dense paclitaxel.

  • Novel trans-ditrifluoroacetato, malonato-1, 4-butanediamine Pt(IV) complex, K104 was synthesized as a chemotherpeutic. The cytotoxicity of K104 against various human cancer cell lines were evaluated by MTS assay in vitro. The IC50 values of K104 ranged 15.83-25.83 $\mu\textrm{M}$, compared to CBCDA ranged 23.24-69.6 $\mu\textrm{M}$. Among several cancer cell lines, K104 showed more potent than CBCDA in colon cancer cell lines. (omitted)

  • DA-125, a novel anthracycline analog containing fluorine with decreased cardiotoxicity and increased antitumor activity of adriamycin (ADM), developed by Research Laboratories of Dong-A Pharmaceutical. DA-125, water soluble prodrug of M1, is a ${\beta}$-alanine derivative of M1 (FT-ADM). DA-125 was rapidly hydrolyzed to M1, and M1 was metabolized to both M2 and M3. (omitted)

  • In a continuous effort to develop novel anticancer agents we newly synthesized and evaluated the antitumor activity of nucleoside analogues. One analogue, 4-[2-Chlor-6-(3-iodo-benzylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentanecarboxylic acid methylamide (LJ-331), has been shown to exert a potent inhibition of human cancer cell growth in vitro including human lung (A549), stomach (SNU-638) and leukemia (HL-60) cancer cells. Following mechanism of action study revealed that LJ-331 induces cell cycle arrest at the G$_1$ phase in HL-60 cells and evokes apoptotic phenomena such as an increase in DNA ladder intensity and chromatin condensation by a dose-and time-dependent manner.

  • Luotonin A was isolated from Peganum nigellastrum Bunge (Zygophyllaceae) which was named Luo-Tuo-Hao in China and used as a Chinese traditional medicine for the treatment of rheumatism, abscess, and inflammation. The basic fractions of P. nigellastrum showed antitumor activtity, and the origin of such an activity was recently revealed by identifying its constituent luotonin A which inhibited the growth of leukemia P-388 cells ($IC_50$ = 1.8 $\mu$g/mL). Such an intriguing properties of luotonin A led developments of efficient methods for total synthesis. (omitted)

  • We have previously reported the synthesis and cytotoxic activities of a series of azaanthraquinone derivatives using doxorubicin as a lead compound. Doxorubicin is known to intercalate into DNA and to inhibit topoisomerase II activity. But in the case of quinone compounds like Dox, its use is limited because of systemic toxicities, primarily cardiotoxicity and myelosuppression. In this study, we discuss the synthesis of isoindolobenzoquinoxaline derivatives. The quinone group of the azaanthraquinone derivatives were removed in the target compounds. (omitted)

  • It is well known that cisplatin. one of chemotherapeutic agents. induces DNA damage and kill cancer cells mainly by apoptosis. We recently synthesized a novel Pt(IV)-based anticancer agent. trans.cis-Pt(acetato)2C12(1.4-butanediamine) (K101) with octahedral structure. To evaluate antitumor activity about human cancer of K101, we have performed histoculture drug response assay in 35 cases of colorectal cancer patients. (omitted)
