Sixteen novel epidermal growth factor receptor (EGFR)/vascular endothelial growth factor (VEGF)-2 inhibitors (nitroimidazole-substituted 4-anilinoquinazoline derivatives (16a-p)) were designed and prepared via the introduction of a nitroimidazole group in the piperidine side chain and modification on the aniline moiety of vandetanib. Preliminary biological tests showed that comparing with vande...

1,2,3-Triazolo[4,5-b]pyridines and pyrazolo[4,3-b]pyridines can be readily prepared via cyanoacetylation reactions of 5-amino-1,2,3-triazoles 1a,b and 4-amino- pyrazole 2 followed by subsequent cyclization of the formed cyanoacetamides. Reactions of amines 1a,b with a mixture of p-nitrophenylacetic acid and acetic anhydride under microwave irradiation conditions afforded the corresponding amide...

Lactonas acetilênicas de tamanho médio e macrocíclico 15a-e [6-decin-9-olídeo (15a), 7-undecin-10-olídeo (15b), 8-dodecin-11-olídeo (15c), 12-hexadecin-15-olídeo (15d) e 5-decin-9olídeo (15e)] foram preparadas a partir de oxabiciclo-alquenonas 7a-d e 2, respectivamente, pela expansão de anel das tosil-hidrazonas 16a-e, efetuada pela reação com N-bromo-succinimida, sob condições rigorosamente co...

Porphobilinogen lactam methyl ester (3a) has been prepared in seven steps, and approximately 20-30% overall yield, beginning with furfurylamine (4a).(24) Hydrolysis of 3a following the literature procedure then gave porphobilinogen (1). A key intermediate in our synthesis of 3a is the 7-oxonorbornene derivative 7a, which was derived from 4a utilizing a tandem Johnson ortho ester Claisen rearran...

Kadmiyumun küçük balmumu güvesi, Achroia grisella Fabricius, 1794 (Lepidoptera: Pyralidae) larvalarının protein, lipit ve karbohidrat miktarlarına etkisi laboratuvar koşullarında araştırılmıştır. Larvalar kadmiyumun üç farklı konsantrasyonu (50, 100 200 mg kg-1 besin) ile kontamine edilmiş yapay besin ortamında yetiştirildi. Kontrol grubundaki böcekler bal peteği (200 g), kepek (860 gliserol (3...

TAT1 (T-type amino acid transporter 1), also known as SLC16A10 (solute carrier family 16, member 10), aromatic amino acid transporter 1, MCT10 (mono carboxylate transporter 10) or PRO0813, is a 515 amino acid protein that belongs to the monocarboxylate porter family. It is a uniporter, which is a Na+-independent transporter of aromatic amino acids (AAA) such as tryptophan, tyrosine, and phenyla...
