まとめ

新しいナノ医薬品は抗炎症薬と化学療法を組み合わせて強力なナノ粒子を生成し結腸直腸がん治療を強化し毒性を軽減し効果を向上させます

科学分野:

ナノテクノロジー
薬物の配達
腫瘍学

背景:

自己組み立てのナノドラッグコンジュガートは標的を絞って腫瘍を投与し,全身の毒性を最小限に抑え,治療効果を最大限に高めます
ナノドラッグの水性および水害性リガンドを組み合わせることで腫瘍を標的とする能力が向上します
非ステロイド性抗炎症薬 (NSAIDs) は抗炎症特性を有しており,抗がん治療を補完する可能性があります.

研究の目的:

新しいアンフィフィリックなNSAID-イリノテカン (Ir) 結合体を合成し,キャリアフリーなナノ粒子に組み立てます.
これらの新しいNSAID- Irナノ粒子の in vitroおよびin vivo抗癌効果を評価する.
最も強力なNSAID- Irコンジュガートの作用の仕組みを調査する.

主な方法:

エステル結合形成による4つのNSAID-Ir結合体の合成
アンフィフィリック結合体とナノ粒子 (NP) に自己組み立ての特徴
HT-29細胞に対する in vitro 細胞毒性測定と HT-29異種移植モデルにおける in vivo 腫瘍成長抑制試験.

主要な成果:

アンフィフィリックのNSAID- Ir結合体は,キャリアフリーなNPに自己組み立てに成功しました.
イブプロフェン- イリノテカン (Ibu- Ir) NPsは,HT-29細胞に対して優れた効能を示した (自由のIrの5. 6倍).
異種移植モデルでは,Ibu- Ir NPsが腫瘍の成長を抑制し,サイクロオキシゲネーゼ- 2とトポイソメラーゼ- Iの発現を抑制することが示された.

結論:

NSAID- IrNPは,大腸がん治療の強化のための有望な戦略です.
Ibu- Ir NPsの抗炎症と抗がん作用の組み合わせは,治療に重要な可能性を秘めています.
このアプローチは,がん治療の改善のための自己組み立てナノドラッグコンジュガートの可能性を強調しています.

Drugs for Treatment of Ulcerative Colitis in IBD

236

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Targeted Cancer Therapies

7.8K

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

5.1K

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

267

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
