Patent number: 9017956Abstract: Provided herein are uses of genes for HOG, Ras and cAMP signal transduction pathways to treat fungal infection. To regulate the HOG pathway of Cryptococcus neoformans, roles of SSK1, TCO2, SSK2, PBS2, HOG1, ENA1 and NHA1 genes were investigated to find that a biosynthesis level of ergosterol is increased when these genes are inhibited. When the genes are inhibited, a large amount of ergosterol is distributed on a fungal cell membrane. Accordingly, since there are many working points of an ergosterol-binding antifungal agent, an efficiency of the ergosterol-binding antifungal agent can be considerably improved. To regulate the Ras and cAMP pathways of Cryptococcus neoformans, roles of RAS1, RAS2, CDC24, GPA1, CAC1, ACA1, PKA1, HSP12 and HSP122 genes were investigated to find that a sensitivity to a polyene- or azole-based drug is increased when these genes are inhibited.Type: GrantFiled: April 15, 2013Date of Patent: April 28, 2015Assignee: Nutrex Technology Co., Ltd.Inventors: Yong-Sun Bahn, Young-Joon Ko, Shin-Ae Maeng, Kwang Woo Jung, Gyu Bum Kim

Publication number: 20120258043Abstract: Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl LeX, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.Type: ApplicationFiled: April 26, 2012Publication date: October 11, 2012Applicant: BRACCO SUISSE S.A.Inventors: Ramachandran RANGANATHAN, Kondareddiar RAMALINGAM, Radhakrishna PILLAI, Edmund R.

Publication number: 20120202756Abstract: The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side-effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.Type: ApplicationFiled: October 5, 2011Publication date: August 9, 2012Inventors: Richard Franklin, Martin Quibell, Robert G. Tyson, Bernard T. Golding
