The present patent application relates to novel binder-drug conjugates (ADCs) of N,N-dialkylauristatins directed against the target epidermal growth factor receptor (EGFR, gene ID 1956), effective metabolites of these ADCs, methods for producing these ADCs, use of these ADCs for treatment and or prevention of diseases as well as the use of these ADCs to produce pharmaceutical drugs for treatment and/or prevention of diseases, in particular hyperproliferative and/or angiogenic diseases such as cancer, for example. Such treatments may be administered as monotherapy or in combination with other pharmaceutical drugs or other therapeutic measures.
The present application relates to new binder-drug conjugates (ADCs) of N,N-dialkylauristatins that are directed against the target C4.4a, to active metabolites of these ADCs, to processes for preparing these ADCs, to the use of these ADCs for treating and/or preventing illnesses, and also to the use of these ADCs for producing medicaments for treating and/or preventing illnesses, more particularly hyperproliferative and/or angiogenic diseases such as, for example, cancer diseases. Such treatments may be practised as a monotherapy or else in combination with other medicaments or further therapeutic measures.
This application relates to a compound of formula I (or a prodrug thereof or a pharmaceutically acceptable salt of the compound or prodrug thereof) as defined herein, pharmaceutical compositions thereof, and its use as an inhibitor of factor Xa and/or thrombin, as well as a process for its preparation and intermediates therefor (I).

A study of the nitrogen inversion process in the bicyclic oxazine, N-methyl-2-oxa-3-azabicyclo[2,2,2]octane, by 13C NMR spectrocopy reveals a free energy of activation of 14.9 kcal mole-1. Detailed examination of the kinetics of the process observed in the 1H spectra of N-methyl tetrahydro-1,2-oxazine shows ΔH≠ 15.1±0.4 kcal mole-1 and ΔS≠ 2.3 ±1.5 cal mol-1K-1. It is concluded from the similarity
通过13 C NMR光谱对双环恶嗪N-甲基-2-氧杂-3-氮杂双环[2,2,2]辛烷中的氮转化过程进行研究,发现其活化能为14.9 kcal mole -1。在N-甲基四氢-1,2-恶嗪的1 H光谱中详细观察该过程的动力学,结果显示ΔH ≠ 15.1±0.4 kcal mole -1和ΔS ≠ 2.3±1.5 cal mol -1 K -1。从活化参数的相似性可以得出结论,这两个过程都是由氮转化引起的。
Efficient cleavage of the N–O bond of 3,6-dihydro-1,2-oxazines mediated by some α-hetero substituted carbonyl compounds in mild conditions
The efficient cleavage of the NâO bond of some nitroso DielsâAlder cycloadducts has been achieved in mild conditions, mediated either by 2,2-dimethyl-1,3-dioxan-5-one or 1,3-dithiolane-2-carboxaldehyde. These new and purely organic conditions allow an excellent tolerance with respect to many functional groups that would have been affected by previous reductive cleavage conditions.
