- ファルネシル基転移酵素(FTase)は、プレニル化によるRasタンパク質の活性化に不可欠です。;以前のファルネシル基転移酵素阻害剤(FTI)は、代償性のゲラニルゲラニル基転移酵素I(GGTase I)活性のため、Ras駆動がんでは失敗しました。;Rasのプレニル化は、細胞シグナル伝達およびがん発生における重要なステップです。
研究 の 目的:
- ファルネシル基転移酵素阻害剤(FTI)に関する最近の進歩をレビューすること。;次世代FTIが耐性メカニズムの克服に成功したことを探求すること。;がん治療を超えたFTIの可能性を議論すること。
主な方法:
- 構造誘導型創薬。;表現型スクリーニング。;創薬のための計算アプローチ。;FTI併用療法の前臨床および臨床研究。
主要な成果:
- 次世代FTIは、選択性の向上とFTase/GGTase Iの二重標的化を示します。;FTIと標的療法または免疫療法の組み合わせは、相乗的な抗腫瘍効果を示します。;FTIは、神経変性疾患、感染症、ウイルス性疾患の治療の可能性を示します。
結論:
- 現代のFTI開発戦略は、初期の阻害剤の限界を克服しました。;次世代FTIは、Ras駆動がんの有望な治療法を提供します。;FTIは、複数の疾患領域にわたる広範な治療的可能性を持っています。

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.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.
