The expression profiles of nine genes encoding chitin deacetylase (CDA)-like proteins were studied during development and in various tissues of the red flour beetle, Tribolium castaneum, by RT-PCR. TcCDA1, TcCDA2 and TcCDA5 were expressed throughout all stages of development, while TcCDA6-9 were expressed predominantly during larval feeding stages. In situ hybridization experiments revealed that b...<br/><br/>Yasuyuki Arakane, Radhika Dixit, Khurshida Begum, Yoonseong Park, Charles A Specht, Hans Merzendorfer, Karl J Kramer, Subbaratnam Muthukrishnan, Richard W Beeman (2009) <i>Insect Biochem Mol Biol</i> 39: 5-6 355-365<br/>

Ion transport peptide (ITP) and ITP-like (ITPL) are highly conserved neuropeptides in insects and crustaceans. We investigated the alternatively spliced variants of ITP/ITPL in Tribolium castaneum to understand their functions. We identified three alternatively spliced transcripts named itp, itpl-1, and itpl-2. Expression patterns of the splice variants investigated by exon-specific in situ hybrid...<br/><br/> Begum K, Li B, Beeman RW, and Y Park (2009) <i>Insect Biochem Mol Biol</i> : <br/>

Atrazine is an extensively used triazine herbicide in agricultural and residential areas and has been routinely detected in many surface and ground waters. This study reveals various up- and down-regulated genes associated with hypoxic stress in atrazine-treated fourth-instar Chironomus tentans larvae (midges) by using restriction fragment differential display-PCR. Two down-regulated hemoglobin cD...<br/><br/>Troy D Anderson, Ying Jin-Clark, Khurshida Begum, Sharon R Starkey, Kun Yan Zhu (2008) <i>Aquat Toxicol</i> 86: 2 148-156<br/>

Photooxygenation of 2-phenylnorbornene 1 in the presence of 30% aqueous hydrogen peroxide afforded 1,2-bishydroperoxide 3, which could be cycloalkylated on treatment with silver oxide and a 1,omega-diiodoalkane to provide the tricyclic peroxides 12. Trimethylsilylation of 3 followed by TMSOTf-catalyzed cyclocondensation with carbonyl compounds led to the formation of the tricyclic peroxides 14 con...<br/><br/>Hye-Sook Kim, Khurshida Begum, Naoki Ogura, Yusuke Wataya, Yuji Nonami, Toyonari Ito, Araki Masuyama, Masatomo Nojima, Kevin J McCullough (2003) <i>J Med Chem</i> <i></i> <i></i> 46: 10 1957-1961<br/>

Among 42 extracts, prepared from 14 medicinal plants used in Vietnamese traditional medicine to treat malaria, 24 were found to have antiplasmodial activity by inhibiting the growth of the chloroquine-resistant Plasmodium falciparum strain FCR-3 with EC(50) values less than 10 microg/ml. Each medicinal plant possessed at least one active extract. The methanol extract of Coscinium fenestratum had t...<br/><br/>Quan Le Tran, Yasuhiro Tezuka, Jun-ya Ueda, Nhan Trung Nguyen, Yukiko Maruyama, Khurshida Begum, Hye-Sook Kim, Yusuke Wataya, Qui Kim Tran, Shigetoshi Kadota (2003) <i>J Ethnopharmacol</i> <i></i> <i></i> 86: 2-3 249-252<br/>

On the basis of a comparative analysis for stability in mouse serum between 15-O-acetylbruceolide and bruceolide 15-methyl carbonate, several 3,15-dialkyl carbonates of bruceolide were synthesized and their in vitro antimalarial activity was assessed. Methyl, ethyl, and isopropyl carbonates with pronounced in vitro activity were further evaluated for in vivo antimalarial potency.

Co(II)-catalyzed peroxidation of dienes including (S)-limonene in the presence of molecular oxygen and triethylsilane provided in each case the corresponding 2,3-dioxabicyclo[3.3.1]nonane derivatives via the intramolecular cyclization of the unsaturated peroxy radical intermediates.

Quinazolinone type alkaloids, febrifugine (1) and isofebrifugine (2), isolated from Dichroa febrifuga roots, show powerful antimalarial activity against Plasmodium falciparum. Unfortunately, their emetic effect and other undesirable side effects have precluded their clinical use for malaria. Because of their antimalarial potency, analogues were searched for, with the goal of preserving the strong ...<br/><br/>Shingo Hirai, Haruhisa Kikuchi, Hye-Sook Kim, Khurshida Begum, Yusuke Wataya, Hidehisa Tasaka, Yuriko Miyazawa, Keisuke Yamamoto, Yoshiteru Oshima (2003) <i>J Med Chem</i> <i></i> <i></i> 46: 20 4351-4359<br/>

We studied sequence polymorphism, expression level of pfmdr1 gene and drug sensitivity in mefloquine sensitive-strain as well as mefloquine-resistant clone/24 to understand underlying drug resistance mechanism. Mefloquine-resistant clone/24 exhibited decreased susceptibility to mefloquine, quinine, halofantrine and artemisinin and increased susceptibility to chloroquine.

Iodonium ion mediated cyclization of unsaturated hydroperoxides 1 afforded the expected yingzhaosu A analogues 2. In some cases, however, the corresponding cyclic ethers 5 were formed competitively with the cyclic peroxides 2, the ratios of these two products being a marked function of the structure of the starting materials. Some of the cyclic peroxides 2 showed significant antimalarial activitie...<br/><br/>Hye-Sook Kim, Khurshida Begum, Naoki Ogura, Yusuke Wataya, Takahiro Tokuyasu, Araki Masuyama, Masatomo Nojima, Kevin J McCullough (2002) <i>J Med Chem</i> <i></i> <i></i> 45: 21 4732-4736<br/>

Drug resistance in Plasmodium falciparum is a serious problem in most endemic areas. Recent studies have suggested the potential involvement of genes in the MDR gene family in resistance to quinoline-containing compounds in P. falciparum. In our present studies, a molecular analysis of pfmdr 1 in isolate strain of P. falciparum, 523a R, from Japanese mefloquine-resistant patient was done to determ...<br/><br/>H S Kim, Y Okuda, K Begum, Y Nagai, Y Wataya, M Kimura, T Huruta (2001) <i>Nucleic Acids Res Suppl</i> <i></i> <i></i> : 1 231-232<br/>

CsOH- or Ag(2)O-mediated cycloalkylation of (alkylidene)bisperoxides 3 and 1,n-dihaloalkanes (n = 3-8) provided the corresponding medium-sized 1,2,4,5-tetraoxacycloalkanes 4-8 in moderate yields. Subsequent evaluation of the antimalarial activity of the cyclic peroxides 4-8 in vitro and in vivo revealed that 1,2,6,7-tetraoxaspiro[7.11]nonadecane 4a has considerable potential as a new, inexpensive,...<br/><br/>H S Kim, Y Nagai, K Ono, K Begum, Y Wataya, Y Hamada, K Tsuchiya, A Masuyama, M Nojima, K J McCullough (2001) <i>J Med Chem</i> <i></i> <i></i> 44: 14 2357-2361<br/>
