再度:

◆ 今 増える  病気:それは 癌 ◆ 

健康意識や医療技術の進歩向上は 健康寿命 を延ばし、

統計上明らかな <平均寿命> の長さに反映されています。

男性は約80才、女性では90才に手が届こうとしています。

その一方で、年々増加する病気があるのも明らかな事実です。

<癌> は今や 日本の 国民病 です。

かつての国民病であった <結核>はなりをひそめ、

<胃癌> も 食生活の改善と 診断技術の進歩、

ピロリ菌対応で、今や決して増加傾向ではありません。

しかし、ある種の癌は増加傾向です。

特に、大腸癌、肺癌、そして 前立腺癌や乳癌 

はこれからも増えていく傾向です。

というのも、癌をみつけやすく、早期対応ができる

ようになっているからです。

 

<うつ病>や<認知症>にかかっている人の数も、過去の数倍に昇っています。

季節性の <花粉症やアレルギー>、<自己免疫疾患>さらには、夏場の 熱中症 なども過去の数をはるかに超えています。生活環境が改善されたために、免疫機能が弱体化し、起こってしまうとも考えられます。

 

今や なおる癌 として取り上げられるのが、乳癌と悪性リンパ腫です。

☆ 乳癌 については、続のようなコメントをする人もいます。

乳癌は女性ホルモンと密接に関係している病気です。


■ 乳癌の増加については、最近の非婚傾向や高齢出産などのライフスタイルや食生活の欧米化が原因に考えられています。食事の影響については、乳がんに限らず、消化器系の癌についてよく言われることです。
感染症などの疾患が撲滅された反面、生活習慣が引き起こす病気が増えている傾向にあります。
乳癌は今後増え続け、2015年には約5万人が乳癌にかかるのではないかと予測されています。

Abstract

Abstract Image
 
 
 
G protein-coupled receptor 40 (GPR40) has become an attractive target for the treatment of diabetes since it was shown clinically to promote glucose-stimulated insulin secretion.
 
 
Herein, we report our efforts to develop highly selective and potent GPR40 agonists with a dual mechanism of action, promoting both glucose-dependent insulin and incretin secretion.
 
 
Employing strategies to increase polarity and the ratio of sp3/sp2 character of the chemotype, we identified BMS-986118 (compound 4), which showed potent and selective GPR40 agonist activity in vitro. In vivo, compound 4 demonstrated insulinotropic efficacy and GLP-1 secretory effects resulting in improved glucose control in acute animal models.

Abstract

Abstract Image
 
 
A series of rhodanines was constructed, their Z-configuration was confirmed by small molecule X-ray crystal structures, and their activity against metallo-β-lactamases (MβLs) was measured. The obtained 26 molecules and a thioenolate specifically inhibited the MβL L1 with an IC50 range of 0.02–1.7 μM, and compounds 2hm exhibited broad-spectrum inhibition of the MβLs NDM-1, VIM-2, ImiS, and L1 with IC50 values <16 μM. All inhibitors increased the antimicrobial effect of cefazolin against E. coli cells expressing L1, resulting in a 2–8-fold reduction in MIC. Docking studies suggested that the nitro (NDM-1, CphA, and L1) or carboxyl group (VIM-2) of 2l coordinates one or two Zn(II) ions, while the N-phenyl group of the inhibitor enhances its hydrophobic interaction with MβLs. These studies demonstrate that the diaryl-substituted rhodanines are good scaffolds for the design of future broad-spectrum inhibitors of MβLs.
