Abstract This research paper describes the synthesis of thermo-reversible cross-linking of sago starch by grafting a furan
pendant group (methyl 2-furoate) onto the starch backbone, followed by a Diels-Alder (DA) reaction of the furan
functional group with 1,1′-(methylenedi-4,1-phenylene) bismaleimide (BM). The proof of principles was provided
by FTIR and 1H-NMR analyses. The relevant FTIR peaks are the carbonyl peak (υ C=O sym) at 1721 cm−1
; the
two peaks appeared after DA cross-linking, i.e., at 1510 cm−1 (corresponding to υ CH=CH BM aromatic rings,
stretching vibrations), and at 1173 cm−1 (assigned to cycloadduct (C-O-C, δ DA ring)) while the 1H-NMR result… More >

Abstract Turpentine is a renewable and resourceful forest product. The deep processing and utilization of turpentine, particularly its primary component β-pinene, has garnered widespread attention. This study aimed to synthesize
40 derivatives of β-pinene, including nopinone, 3-cyanopyridines of nopinone, myrtanyl acid, myrtanyl
acylthioureas, and myrtanyl amides. We assessed the antiviral activities of these β-pinene derivatives against influenza virus A/Puerto Rico/8/34 (H1N1) using the 3-(4,5-dimetylthiazol-2-yl)-2,5-diphenyltetrazolium bromide
