Hijji, Yousef; Elsafi, Anas; Al Easa, Hala; Attili, Bassam; Abdelrasoul, Mahmoud; Mohamed, Nura; Nasrallah, Gheyath... more authors ... less authors ( Royal Society of Chemistry , 2019 , Article)Curcumin, 1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-hepta-diene-3,5-dione, is a natural product obtained from the rhizome of Curcuma longa. Curcumin has been demonstrated to be a strong antioxidant with anticancer properties ... -
(E)-2-{[(Furan-2-ylmethyl)imino]methyl}-4-nitrophenol
Hijji, Yousef; Azemati, Samira; Butcher, Ray J.; Jasinski, Jerry P. ( International Union of Crystallography , 2014 , Article)In the title compound, C12H10N2O4, the furan-2-ylmethyl group is disordered over two sets of sites, with refined occupancies of 0.858 (3) and 0.143 (3). In the major component of disorder, the dihedral angle between the ... -
Natural Dyes in Cyanide and Anion Sensing
Hijji, Yousef; Al Easa, Hala Sultan; AbdelRasoul, Mahmoud ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Cyanide is one of anions of concern due to its high toxicity. It causes death at a low dosage (2.6 mM) and the allowable level should be lower than 1.9 mmolar according to World health Organization (WHO). Cyanide contamination ... -
A novel approach of encapsulating curcumin and succinylated derivative in mannosylated-chitosan nanoparticles
Idoudi, Sourour; Hijji, Yousef; Bedhiafi, Takwa; Korashy, Hesham M.; Uddin, Shahab; Merhi, Maysaloun; Dermime, Said; Billa, Nashiru... more authors ... less authors ( Elsevier , 2022 , Article)Curcumin (CUR) manifests anti-colon cancer activity but suffers from low solubility, bioavailability, and instability, rendering it not as effective as its chemotherapeutic cousins. Here, we conjugate CUR to succinic ... -
Studies on anti-colon cancer potential of nanoformulations of curcumin and succinylated curcumin in mannosylated chitosan
Sourour, Idoudi; Bedhiafi, Takwa; Sahir, Fairooz; Hijji, Yousef; Uddin, Shahab; Merhi, Maysaloun; Dermime, Said; Billa, Nashiru... more authors ... less authors ( Elsevier , 2023 , Article)Colon cancer (CRC) is the second leading cause of death and the third most diagnosed cancer worldwide. Although curcumin (CUR) has demonstrated a potent anticancer activity, it is characterized by its poor solubility, low ... -
